Tomàs pregunta ...

Vostè dóna suport l'energia nuclear? Per què o per què no?

Jo personalment el seu suport.
A causa que:
Aquí a Austràlia, tenim una gran quantitat d'urani de manera que també pot guanyar diners exportant a altres països.
No genera diòxid de carboni tant com, per exemple, el carbó que és també una font no renovable.
Vostè pot produir una gran quantitat d'electricitat en una sola planta.

Però no estic ignorant el fet que l'energia nuclear és, com tota la resta, no són perfectes.
L'emmagatzematge dels residus és un problema, i també ho és el fet que és una operació arriscada.

Però si ens fixem el problema de les escombraries a un costat per un moment, la cosa arriscada operació no és realment d'una gran quantitat.
Vull dir que si ens fixem en la vida quotidiana, hi ha una major possibilitat de persones que moren en accidents automobilístics (alguna cosa que es fa gairebé cada dia és el passeig en un cotxe) que de ser matat per la crisi / accidents d'una central nuclear.

Tot i que l'urani no és renovable i que només estarà disponible per a un màxim de 100 anys, segueixo pensant que és una millor opció en comparació amb el carbó, etc, perquè el que realment fa una diferència a l'emissió de diòxid de carboni.

Comparteixi les seves opinions per favor i donar les raons. :)
@ Poc
Entenc que vostè està venint, però en comparació amb el carbó, quin triaria?
Jo mateix preferiria si fem servir l'energia eòlica o la solar, ja que són lliures de risc, les fonts renovables, però en aquests moments estem confiant en el carbó en la seva majoria.

S'està produint una gran quantitat de diòxid de carboni que contribueix a l'escalfament global.

Les respostes d'experts:

Estic d'acord amb tu, per les mateixes raons.

Laura li pregunta ...

Són les cèl · lules de combustible d'una economia falsa?

Tothom sembla estar molt estimulada per la revolució de l'hidrogen se suposa que està a la volta de la cantonada. Cotxes de piles de combustible alimentades, se'ns promet, serà del 100% amb aigua només com un producte de rebuig. Se'ns diu que les piles de combustible es podrà tot, des automòbils fins ordinadors portàtils.

Algú més veu problemes amb aquesta proposta? En primer lloc, l'hidrogen és un gas molt volàtil, de manera que omplir els cotxes, etc amb ell serà molt més perillós que omplir amb gasolina. A més, si un cotxe ple d'accidents de gas d'hidrogen i es va trencar el tanc d'emmagatzematge, tot això va a explotar al primer senyal d'una espurna.

En segon lloc d'hidrogen, no es produeix en grans quanities natural, de manera que hem de produir. Això requereix d'energia i, segurament, aquesta energia és només va a provenir de la crema de més combustibles fòssils en centrals elèctriques. I si no ho fa, si hem creat una infraestructura d'energia renovable, per què tan sols necessita d'hidrogen? tot (incloent vehicles, etc) només pot ser connectat a una presa de corrent ...

Les respostes d'experts:

L'eficiència de combustible de cèl · lula de motor de conversió d'energia és sens dubte molt més gran que la de motors de combustió interna o motors de vapor. El cost del sistema de cèl · lula de combustible és també innegablement molt major que la d'IC ​​o màquines de vapor.

Des Enginyer Visió:
"Moltes empreses d'automòbils en marxa de combustible dels vehicles de cel · les de prova per mostrar a l'última cèl · lula de combustible avançada tecnologia. Un bon exemple és el de Daimler Chrysler Necar. L'última és Necar Necar 5. El 4 de juny de 2002, Necar 5 completat un recorregut històric de 16 dies des de San Francisco a Washington, DC Va ser el primer intent de conduir un vehicle de pila de combustible als EUA ".

Des de Nova York, Nova York a San Francisco, Califòrnia, és de prop de 2930 milles. A una velocitat mitjana de 50 quilòmetres per hora i dia de conducció mitjana de 10 hores. (500 milles / DA), aquest Thip ha de tenir 6 dies per conduir amb relativa comoditat.
El cotxe de pila de combustible mitjana de 184 km / da, de manera que un temps considerable que s'han gastat en la promoció, o el cotxe va ser molt lenta, donades les condicions reals de conducció. Es pot aconseguir aquesta mitjana amb un Model T.

La producció d'hidrogen com a combustible a gran escala és molt costós i ineficient ús de les tecnologies actuals. La proposta més popular és la reducció dels combustibles d'hidrocarburs, que segueix els mateixos problemes de contaminació que tenim avui, encara que sigui més fàcil de tractar. Els òxids de carboni, nitrogen, sofre i altres contaminants han de ser esborrat a terme i rebutjat de forma segura. Per ser eficaç, l'hidrogen ha de ser comprimit i emmagatzemat en cilindres d'alta pressió, després es distribueix a "gasolineres". Aquesta tecnologia existeix, i necessita ser gastat només. El perill que representen els cilindres de gas H2 no és major que la plantejada pels actuals GLP (propà o butà) o gas natural liquat (metà), els tancs, i en realitat és molt menor que la proporcionada per un dipòsit de gasolina mig ple.

Amb el temps anem a recórrer a electrolosys d'aigua per produir hidrogen. Les nostres opcions de fonts d'energia serà nuclear, solar, eòlica, geotèrmica i les marees. D'aquests, només nuclear té alguna esperança de proporcionar l'energia necessària sense la destrucció irreparable als nostres ecosistemes. Amb sort, quan vam arribar a aquest pas anem a dominar les reaccions controlades de fusió.

Vehicles totalment elèctrics són inacceptables, ja que estan limitats en abast, velocitat i resistència. Els híbrids s'estan produint, i vehicles de prova han rebut una àmplia acceptació (un subjecte de la prova es va negar a renunciar al seu vehicle després de la prova.).

Lisa li pregunta ...

Deu punts!?

Dissenyat per Peter Poulet i Michael Harvey, la Casa de formigó celebra el formigó com un material fort. Per
usant components fàcilment disponibles i transportable aquesta casa és assequible, ràpida de construir, i no es basa en
treballadors molt especialitzats. El formigó és un material durable que requereix molt poc manteniment.
Viure en aquesta casa seria un compromís de viure de manera sostenible, ús d'energies renovables, la recol · lecció d'aigua de pluja
i minimitzar els residus. Emmagatzematge d'aigua de pluja està integrat en el disseny usant les columnes de formigó prefabricat
- Gairebé qualsevol volum d'aigua que poden ser emmagatzemats usant aquest senzill mètode. Un sistema solar d'aigua calenta es pot instal · lar
al sostre. Natural de la massa tèrmica del formigó s'utilitza per mantenir la casa fresca a l'estiu i càlida a l'hivern.

Daniel li pregunta ...

Què ens passa als centenars de milers de milions de dòlars abans de la guerra.?

D'alguna manera l'assumida per moltes persones que la fi de la guerra milloraran les nostres vides d'alguna manera.
Sabia que gastem 20 mil milions de dòlars per a la cura del càncer o invertir en la producció d'energia renovable, o fins i tot donar una bona cura de criança dels nens per assegurar que cap d'ells s'abusa.

No ho crec.

Què és el que gastem els diners.

Ponts enlloc, les oficines de correus, canvi de nom dels aeroports privats, cases rodants de FEMA que se sentin buits podrint i lloguer d'espai d'emmagatzematge per emmagatzemar els béns donats per als esforços d'ajuda que haurien d'haver estat dispersades a les víctimes de l'huracà.

Hem gastat milions en estudis per determinar la millor manera de reconstruir la devastada costa del Golf i, no obstant això fins ara només uns pocs milers d'habitatges han estat reconstruïdes.

Perquè la gent pensa que el govern hagués gastat aquests diners en alguna cosa que no sigui ell mateix i les necessitats dels rics és una tonteria.

Crec que la guerra dóna treball a molts dels que no tenen cap.

La vida és perillosa i més persones moren en accidents de trànsit a continuació, en la guerra.

Heus aquí les estadístiques reals del Departament del Tresor, l'Oficina del deute públic. Sembla que la gent realment no sap el que són, o fins i tot tenir una pista.

-Acaba d'afegir per a l'home sota meu-

Recordeu que vaig dir "per sota" de mi. Potser hauria d'haver dit per sota de ... de totes maneres. He fet 2 tours a l'Iraq i un a Kosovo, Macedònia i Bòsnia. No pretenc parlar amb mi sobre els militars. Si algú té un familiar o amic que ha mort a la guerra, no cal fer un flac favor al dir aquestes coses. Tingueu una mica de respecte. Només perquè ets massa d'un pensament a signar i lluitar per tu mateix. Ets tan ingenu que no sap que els soldats es va inscriure per a la guerra? L'explicaré a vostè, això és el que fan els soldats, es barallen les guerres. Espero que almenys aquesta part té sentit. Ens ha alliberat 24 milions de persones innocents. Hem guanyat la guerra a l'Iraq. Els mitjans de comunicació simplement no volen a les masses ignorants, com vostè, per saber d'ell fins després d'haver votat per Obama. No siguis tan ingenu.

Quant a la deficitària del pressupost i el deute se'n va, que està dictada per l'economia. L'economia fa el que li plagui i no li importa qui és el president.

Ruth li pregunta ...

que sigui senzill per a mi?

L'energia hidroelèctrica es produeix en centrals hidroelèctriques. Energia Hidroelèctrica d'energia hidràulica significa també conegut com la força o l'energia de l'aigua en moviment. Es tracta d'una font d'energia renovable no produeix residus i diòxid de carboni que ajuda a gasos d'efecte hivernacle (gasos presents en l'atmosfera que redueixen la pèrdua de calor). L'energia hidroelèctrica prové de l'energia potencial de l'aigua embassada de conduir una turbina d'aigua (motor que pren l'energia de l'aigua en moviment) i el generador (un dispositiu que converteix l'energia mecànica en energia elèctrica). L'energia extreta de l'aigua depèn del volum i la diferència d'altura entre la font i la sortida de l'aigua. Aquesta diferència d'altura es diu el cap. Energia hidroelèctrica per bombament produeix electricitat per proveir la demanda pic d'alta pel moviment de l'aigua entre els dipòsits (un lloc o recipient buit on es guarda alguna cosa (generalment líquid) en la reserva, per al seu ús posterior) a diferents alçades. En els moments de demanda elèctrica baixa, l'excés de capacitat de generació s'utilitza per bombar aigua al dipòsit superior. Quan hi ha una major demanda, l'aigua es retorna al dipòsit inferior a través d'una turbina.

Les respostes d'experts:

Hi ha una planta d'energia hidroelèctrica al nord de Gal · les, Regne Unit, que fa més o menys el que la seva escriptura-up diu.
Hi ha 3 grans turbines d'aigua que prenen l'aigua d'una presa de 600 peus per sobre de la planta per fer funcionar els seus generadors respectius.
A la sortida de les turbines, l'aigua flueix a un altre llac a sota de la planta.
Durant el dia (06 a.m. a 20:00), els generadors estan produint energia al Sistema Interconnectat Nacional en el cost màxim als consumidors.
Durant la nit, quan els costos de electricicty són molt menys, els generadors es converteixen en els motors i la marxa enrere en la seva rotació. Les turbines estan alineats en sèrie. El sistema es posa en marxa les turbines de les bombes i convertir-se, l'aigua del llac menor es bomba de nou cap al llac més alt durant la nit.

Llavors, què, si es tallar i enganxar el text que vostè té.
He visitat la instal · lació anterior (sóc un Brit), i és ni més ni menys que un lloc increïble per visitar.
La planta de turbines de generació Disposa de servei estan construïdes en una muntanya ... Una mica de James Bond-ish ", però, és un fet ... una fantàstica posada a punt.

Linda pregunta ...

escriure un comentari sobre FETS DE RECICLATGE I BENEFICIS?

Avui tothom ha sentit parlar de la importància de reciclar i la majoria de les ciutats ofereixen un programa de reciclatge, però què és el reciclatge i el beneficiós que és realment per a nosaltres i el medi ambient?

Quins són els fets de reciclatge i els beneficis?
El reciclatge és el procés de convertir un producte peces útils en un nou producte, això es fa per estalviar en el consum de recursos, l'energia i l'espai utilitzat en els abocadors.
Al reciclar 1 ampolla de plàstic no només estalvia entre 100 i 1000 anys a l'abocador sinó que també estalvia el medi ambient de les emissions en la producció de noves ampolles, així com l'oli usat per produir l'ampolla.
Per cada tona un de plàstic que es recicla s'estalvia l'equivalent del consum d'energia de 2 persones per 1 any, la quantitat d'aigua utilitzada per una persona en temps de 2 mesos i gairebé 2000 lliures d'oli.
Aproximadament el 60% de les nostres escombraries tirat avui podrien ser reciclats. Es va realitzar una enquesta i 9 de cada 10 persones enquestades van dir que reciclar més, si era més fàcil.

Per estrany que sembla que hi ha molta gent que no s'adonen que les ampolles de plàstic l'aigua entra en està fet de petroli. Aquest és el mateix oli que s'utilitza per produir gasolina. És el mateix oli que es troba en gran demanda i no és un recurs il · limitat.
Avui dia els productes més comuns a les ciutats dels programes de reciclatge són els productes de paper, cartró, plàstic, vidre i alumini.

Prenent només un moment per posar en el seu diari, una llauna de soda i pot de vidre espaguetis a la paperera de reciclatge s'estalvia tot el món l'any el dany ambiental de la producció de nous materials, sobre els abocadors plens de gent i l'esgotament dels nostres recursos naturals.
4000 anys

Quan no reciclar almenys el nostre vidre o alumini que costa la terra en l'ús d'energia d'ús, l'aigua i l'oli i la utilització de farcits sanitaris, vidre triga fins a 4000 anys en descompondre en un abocador però, es pot reciclar indefinidament.

Guanyar Diners
El reciclatge pot ser fet a casa, així com en relació amb els programes de la ciutat. Moltes iardes de la ferralla pagar per ferralla incloent les llaunes de refresc i llaunes de sopa que usem cada dia.

Sigui creatiu
Molts articles útils es poden fer de les escombraries cada dia, els tubs de cartró sobrants de paper tovallola i paper higiènic pot fer que els recipients d'emmagatzematge d'estris per als nostres cables d'extensió addicionals i impedeix que un embull dels llums de Nadal. Si tu vas a llançar aquests cap a fora no només llençar-la, ja que la paperera de reciclatge.

Flascons per a nadons poden arribar a ser globus de neu dels nens poden fer i donar com a regals, targetes de nadal pot arribar a ser les noves targetes fetes a mà i un got o una ampolla de plàstic juntament amb una mica d'oli clara i colorant d'aliments i alguns altres elements comuns de la casa pot esdevenir una renta meravellós llum!
Les possibilitats són infinites i les instruccions es poden trobar en llibres ia Internet.

Comenceu avui
El reciclatge és una activitat molt verd el medi ambient, però, hi ha maneres que vostè pot fer que sigui més verd, així com la construcció d'un sòlid començament si no es reciclen actualment.
Moltes persones que comencen un programa de reciclatge de mirar al voltant i es pregunten què poden posar en el recipient de reciclatge, no hi ha tanta informació disponible en aquest lloc, així que no s'estengui el pànic.
Mitjançant la reutilització dels envasos d'emmagatzematge reciclats a estalviar en l'impacte ambiental també. Les bosses de paper i plàstic són bons per al reciclatge d'emmagatzematge, però, una safata de plàstic reutilitzable és encara millor.

Corre la veu!
Comparteix el que saps. Si s'observa les escombraries abunda al barri comença a escampar la paraula i la seva experiència amb el reciclatge i si no és ja un en el seu lloc s'esforcen per aconseguir un reciclatge de la ciutat recull el programa va començar.

El fet és que molts dels nostres recursos, així com la nostra Terra no és renovable i hem de començar a prendre el control de nosaltres mateixos a partir del món en què vivim

L'escalfament global ja no es considera com una teoria dels científics i s'ha convertit tristament en un fet. El canvi necessari ha d'estar en les seves accions d'avui amb la finalitat d'assegurar un brillant (no gaire calenta) de matí.

Les respostes d'experts:

Bé, em vaig tallar els llençar escombraries en un 50%!

Vaig començar a beure cervesa de 24 oz Llaunes, així que ara només es tiren tres llaunes de la finestreta del cotxe en comptes de sis!

No m'ho agraeixi ... Només estic fent la meva part.

Les respostes d'experts:

Això és una estafa - ni d'ells són legítims Hewlett Packard adreces de correu electrònic. Si no acaba in@hp.com que no es tracta de l'empresa real

Això no és més que una estafa per robar el temps la totalitat dels seus diners i cometre robatori d'identitat amb les seves dades. Se li demanarà que envieu una còpia del seu passaport en alguna "agència" per processar la visa, i després demanar diners. A continuació, demanar més diners per a un altre certificat. A continuació, els diners més que més, fins que finalment despertar i adonar-se que ha estat una estafa tot el temps

Eliminar aquest o informar a qualsevol agència al seu país s'ocupa de la delinqüència a Internet

Una important companyia global com HP mai va a oferir un treball a través d'Internet. Si no van ser traslladats al Regne Unit per a una entrevista a la seva oficina principal a Bristol (no està a Londres), llavors el treball no existeix. Una empresa no pot obtenir un visat per a una persona que mai ha conegut en persona. Aquest és un dels requisits de l'empresa ha de demostrar - que o bé han volat a que coneguis o que a l'avió per complir amb almenys 2 entrevistes abans que se li pot oferir la feina i patrocinar un visat

Josep li pregunta ...

L'energia renovable ideal - turbina de vent a les rodes per obtenir el poder de l'huracà?

És possible aconseguir una turbina eòlica gegant amb rodes que es poden col · locar en els huracans per tal de recollir grans quantitats d'energia?

Per exemple, què tal una turbina molt resistent (com la hèlix que es faria servir per als avions que van 500 MPH) i un dispositiu d'emmagatzematge d'energia que converteix l'òxid d'alumini d'alumini (material d'alt potencial d'energia / energia alliberada = reacció de tèrmit), per exemple. Amb l'hidrogen, que malgasten energia comprimint ... així que preferiblement un sistema de conversió d'energia que dóna sòlids o líquids. A continuació, només bombar el combustible a qualsevol lloc i convertir-lo en electricitat.

SI??
Per descomptat, vostè tregui les llantes i tancament d'una vegada el lloc ... materials per a la construcció pot ser molt barat crec que si REALMENT tractat de construir amb peces ja fetes.

Les respostes d'experts:

No és possible fer fortes les turbines suficients suficients i grans que també són portàtils, i de qualsevol manera, els huracans no ocorren amb suficient freqüència. I només imaginar la quantitat de combustible i el nombre de treballadors i el temps que es necessita per moure aquestes màquines gegants! És molt millor per a construir milers de turbines instal · lats de forma permanent en llocs que veuen als vents moderadament forts la major part de l'any. Els vents prou forts per fer un munt de poder, però no tan fort com per fer mal les turbines. Els vents que bufen gairebé cada dia i els dies no només un o dos dels anys. Això s'està fent ja.

I les seves idees d'emmagatzematge d'energia sonar com que es guardi molt poca energia i requereix una gran quantitat de problemes per dur a terme.

Joan pregunta ...

quin tipus de planta és la planta d'energia nuclear Turkey Point a Homestead Florida?

és o bé BWR o PWR?

Les respostes d'experts:

Turquia, la planta nuclear és un punt de PWR (reactor d'aigua pressuritzada), però les instal · lacions el 30 de juny 2009 es va presentar una sol · licitud per construir dos de 1.550 MWe ESBWR (econòmics reactors simplificats d'aigua en ebullició), de manera després de la finalització dels reactors de prop de 2017. Turquia riu seria tant un reactor d'aigua pressuritzada (PWR) i un reactor d'aigua en ebullició (BWR)

Betty li demana ...

Anem a veure les noves centrals nuclears construïdes en el futur proper?

En l'exemple més recent dels sorprenentment cars noves centrals nuclears,

"El govern d'Ontario va posar els seus plans d'energia nuclear en espera el mes passat pel fet que l'oferta d'Atomic Energy of Canada Ltd, l'únic" conforme "un d'ells va rebre, va ser més de tres vegades superior al que la província ha de pagar [en $ 13 mil milions de dòlars reactor].

Això significa que un sol projecte hauria acabat amb la província nuclears -. Pressupost d'expansió de l'energia per als propers 20 anys, deixant sense diners almenys altres dos projectes de rehabilitació de milers de milions de dòlars "

"Gran part de l'augment de preus dramàtica es relaciona amb el cost de la mà d'obra i materials, que s'han disparat en els últims anys. De Subministradors Nuclears i els seus inversors també tenen menys tolerància al risc."

http://www.thestar.com/comment/columnists/article/665644

Així mateix, Turquia no va poder obtenir cap oferta per sota de 21 centaus de dòlar per kWh per una arma nuclear nova (el cost de l'energia mitjana és actualment de menys de 8 centaus de dòlar per kWh).

http://www.todayszaman.com/tz-web/detaylar.do?load=detay&link=164556&bolum=105

Una nova arma nuclear a Finlàndia va passar per sobre del pressupost en més de $ 2 mil milions (50% sobre l'estimació inicial) i 3 anys més del previst.

http://www.reuters.com/article/rbssIndustryMaterialsUtilitiesNews/idUSLS56745220080828

En l'energia nuclear de nova EUA està en camí de costar 15 centaus a 20 centaus de dòlar per kilowatt-hora. I cap planta nuclear ha dut a terme dins del pressupost.

http://www.time.com/time/printout/0, 8816,1869203,00. html

Florida Power and Light va arribar a la conclusió que dues noves unitats per un total de 2.200 megawatts costaria $ 12 mil milions a $ 18 bilions.

Reguladors de Progress Energy informar de l'estat que els bessons de 1.100 megawatts plantes que té intenció de construir a Florida costaria $ 14 mil milions, el que "triplica les estimacions de la utilitat que ofereix poc més que fa un any." I les seves estimacions de costos són "no vinculant" i "subjecte a canviar amb el temps. "

http://climateprogress.org/2008/06/13/ nuclear - el poder-part-2-el-preu-is-not-a la dreta /

Amb aquests costos molt alts per a les noves centrals nuclears a tot el món, creus que anem a veure les noves centrals nuclears construïdes en el futur proper?

Les respostes d'experts:

Crec que depèn de la quantitat que el govern federal subsidiàries. Els EUA ja ha posat més de $ 100 mil milions (article de Time). El racional era originalment per promoure una indústria incipient. No obstant això, les nuclears 'ales' encara no suportar el seu pes.
I això sense comptar el cost de l'eliminació permanent dels residus nuclears, que és molt car. La planta de Yucca Mountain està en espera, perquè els residents de Nevada no vol les escombraries "en el vostre jardí". Per tant, ha mantingut molt més a prop teu que Yucca Mountain és la majoria dels residents de Nevada.
Qui calcula el cost d'extrem a extrem de combustible nuclear? Es necessita molt petroli per produir el combustible llest per entrar en el reactor, i deixa darrere seu un embolic de deixalles radioactives.
Three Mile Island bancs descoratjats accidents de la indústria de finançament. Els excessos en els costos i els tumults polítics en els anys 70 i 80 ..
Així que a menys que la idea d'Uncle Sam subsidiar plantes d'energia en gran mesura aconsegueix la tracció, no crec que hi hagi centrals nuclears construïdes aquí.
Ah, i Alemanya, acaba de tenir un accident (Krummel), inclosos els danys en el nucli.

David li demana a ...

Per què no els defensors de la potència global de suport escalfament nuclear?

Això sempre m'ha desconcertat, perquè la majoria dels defensors de l'escalfament global són escèptics perquè tenen por al seu baix cost i l'eficiència de l'energia nuclear.

Però es podria pensar, si aquest fos el cas, en la seva majoria estaria a favor del canvi per reduir el consum de combustibles fòssils barats com el carbó i el gas natural. No obstant això, la majoria dels autors semblen resistir-se a tot cor un major ús de l'energia nuclear.

Això sembla contradir les seves motivacions ecològiques, ja que l'energia nuclear nova és extremadament eficient i neta. Una de les poques noves plantes d'energia nuclear proposat per a ser construït en els EUA en els últims 30 anys - en Sant Antoni - es va estimar originalment a un cost de $ 13 mil milions per 2 reactors. El preu acaba de pujar altres $ 4000000000 causa dels sindicats i les regulacions de l'EPA sense fonament.

http://www.mysanantonio.com/news/ nuclear ...

La mateixa història es pot aplicar a les propostes de les centrals nuclears a Florida, Carolina del Nord, ia l'estranger al Canadà i Finlàndia. A causa principalment a l'EPA i els defensors de l'escalfament global, l'energia nuclear està molt reprimida alternativa viable.

No obstant això, sentim constantment a les preguntes dels defensors de l'escalfament global sobre per què els no creients no són compatibles amb algore i l'església de l'escalfament global amb més força.

Quin és el problema? No entenen la realitat del poder nuclear neta i eficient? No ho resisteixen perquè els no creients saben l'energia nuclear és millor que el carbó i el gas natural? ¿S'acaba de repetir com a lloros el que escolten dels mitjans de comunicació liberals i els llocs web polítics?

Les respostes d'experts:

Tenen por que una central nuclear es construirà en el qual es pot veure, i no es veuen molt bé. Òbviament, la solució és construir al pati del darrere escèptic AGW, que els alarmistes veuen com just. No obstant això, la resta de nosaltres no està d'acord amb els alarmistes, de manera que sent la necessitat d'eliminar totes les centrals nuclears, ja que no tots estan d'acord amb els alarmistes sobre els mateixos.

Tots vostès pensen que estic fent broma, oi? Ted Kennedy refused to have a wind farm built near his property, because it would disrupt his view. Same thing with liberal Sen. John Warner, who tried to bar the Army Corps of Engineers from permitting offshore windfarms, as he and his relatives all live on the coast. Clearly, all the alternative power plants belong in the west, so that they can disrupt the view of people that don't matter (particularly conservatives).

Just imagine what it'd be like if you replaced the windmills with a massive nuclear power plant belching clouds of steam.

Steven pregunta ...

Why do global warming 'skeptics' support nuclear power so strongly?

This has always puzzled me, because most AGW deniers are 'skeptics' because they're afraid of the economic costs of carbon regulation.

But you would think if that were the case, they would mostly favor the status quo of relying on cheap fossil fuels such as coal and natural gas. Yet most 'skeptics' seem to wholeheartedly support an increased use of nuclear power .

This seems to contradict their economic motivations, because new nuclear power is extremely expensive. One of the few new nuclear power plants proposed to be built in the US in the last 30 years – in San Antonio – was originally estimated to cost $13 billion for 2 reactors. The price tag just went up another $4 billion.

http://www.mysanantonio.com/news/Nuclear_cost_estimate_rises.html

The same story can be applied to proposed nuclear plants in Florida , North Carolina, and abroad in Canada and Finland. Due mainly to increased construction costs, nuclear power is an expensive alternative.

Yet we constantly hear questions from deniers about why “alarmists” don't support nuclear power more strongly.

What's the deal? Do they not understand the reality of nuclear costs? Do they support it just because environmentalists used to object to nuclear power ? Are they just parrotting what they hear from the right-wing media?
Looks like it's indeed a combination of my suspicions.

1) They're purely anti-environmentalists.
2) They're purely anti-liberal, and view renewable energy as “liberal” and nuclear as “conservative”.
3) They're stuck in the 1970s and think nuclear power is still cheap.

Or some combination of the three.

The Expert answers:

I think history plays a role in this. Most global warming deniers are on the political right. In the 1970′s-1980′s, many environmentalists had concerns over nuclear power, which eventually lead to stricter regulation. Environmentalists had been supporting renewable energy. Many on the right were angered that environmentalists were successful at influencing policy and blamed them for slow growth of nuclear power, even though much of the reason for that was rising nuclear costs, and plunging fossil fuel prices. So US Republicans believe they “own” nuclear power and see renewables “owned” by liberals. Their support for nukes is like cheering for a team. The fact that nuclear power is quite expensive eludes them. They want to push nuclear power so they can feel like they finally beat those pesky environmentalists that thwarted them in the 1970′s. In other words, they are living too much in the past.

Nuclear power is an effective global warming solution and independent of that, has much fewer environmental problems than coal. If they can get the costs down and economically compete with renewables such that they are clearly and consistently cheaper (nukes no doubt have more environmental and national security costs than renewables), more “power” to them.

Sharon demana a ...

How can we rely on increased nuclear power production given its cost?

Florida Power & Light estimated that building a new nuclear plant in that state would cost $12-18 billion. A new study concluded that generation costs from a new nuclear power plant would cost 25-30 cents per kWh – three times the current average US electrical rates. A June 2008 report by Moody's Investor Services Global Credit Research concluded that any utility engaging in the risky venture of building a new nuclear power plant would experience a severe decline in its credit rating.

http://climateprogress.org/2009/01/07/ nuclear - power - plants -troubled-assests-credit-risk/#more-4585

Now I want to point out that I'm not suggesting we shut down all nuclear plants and never use nuclear power again. However, many people seem to feel that nuclear power is a silver bullet which will solve all our energy problems. Given the costs and risks of new nuclear plants , it seems more like a diamond-encrusted platinum bullet to me.

So how can we rely on increased nuclear power production to solve our energy problems given its cost and risks?
Ben – solar and wind (and geothermal) are cheaper, as discussed here:

Linda pregunta ...

How does Turkey Point Nuclear Power Plant dispose of it's nuclear waste?

Located in Florida ?

The Expert answers:

Ever had a double down?

Jenny asks…

Why is the GOP pushing for new nuclear power?

“Republicans say, build 100 new nuclear power plants during the next twenty years”

http://www.gop.com/News/NewsRead.aspx?Guid=92504368-37ec-4d4e-94bb-9edc4fc33250

But as they push for a massive number of new nuclear plants , this is what's happening around the world.

Finland: “After four years of construction and thousands of defects and deficiencies, the reactor's 3 billion euro price tag, about $4.2 billion, has climbed at least 50 percent. And while the reactor was originally meant to be completed this summer, Areva, the French company building it, and the utility that ordered it, are no longer willing to make certain predictions on when it will go online.”

Turkey: “The only company bidding…offered a price of 21.16 cents per kilowatt-hour (kWh). Current electricity prices in the country vary between 4 cents and 14 cents per kWh.”

http://www.todayszaman.com/tz-web/detaylar.do?load=detay&link=164556&bolum=105

Even here in the USA, in Florida : “Progress Energy offered its revised estimate Tuesday: $14-billion for two new nuclear reactors…The utility said its 200-mile, 10-county transmission project will cost $3-billion more. The total cost triples estimates the utility offered little more than a year ago.”

http://www.tampabay.com/news/business/energy/article414653.ece

Idaho: “Consumers expect reasonably priced energy, and the company's due diligence process has led to the conclusion that it does not make economic sense to pursue the project at this time,” Bill Fehrman, President of MidAmerican Nuclear Energy Co, said in the letter to Payette County residents.

http://www.reuters.com/article/companyNews/idUSN2957446620080129

The list goes on. Why does the GOP want 100 new nuclear power plants when currently they're so expensive and having so little success in the USA and around the world?

The Expert answers:

Well, call me a crazy conspiracy theorist, but I think it has something to do with the centralization of power. Read whatever you like into that statement. What other possible explanation can there be for their vehement opposition to distributed [anything]?

We could actually have clean efficient nuclear power with gen IV designs that can actually burn nuclear “waste”. But this type of nuclear infrastructure would turn nuclear power into a kind of public trust – the last thing they want.

When you can't centralize and control and take all the profits and funnel them upwards – they want nothing to do with it. More than that, they want to quash distributed infrastructure of any sort, lest the little people get the idea that they can have some measure of control over their own lives and destiny. I think people are starting to wake up to what happened in the last century. I think it's telling that the new administration gave more of GM to the unions than to the bondholders. It's a beginning of a return to some sort of balance.

I like your explanation from before – nuclear is pointless when renewables (even centralized renewables) are cheaper. However, if we don't do demand management in a big way, like an Apollo program that cuts energy use in half in 10 years, the demand growth for energy coupled with realization that carbon is destroying the climate may make nuclear inevitable – because without demand management renewables can't satisfy the load. Or can they?

Light water reactors are one of our most dangerous, inefficient, wasteful and unsustainable technologies. We mine the uranium at tremendous (social and environmental) cost. We only have enough uranium for 70 years anyway. We use it once leaving 99% of the energy behind turning it into a 100,000 year nightmare of highly radioactive, highly toxic waste. All the light water reactor waste ever created is still there, in holding ponds, at the power plants where it was created.

“…some form of molten-salt thorium breeder could be the most efficient well-developed energy source known, whether measured by cost per kW, capital cost or social costs.”

But we don't do it. The party of dumb wants more light water reactors. Per què? See above and some of the other salient answers.

Daniel li pregunta ...

Why Not Nuclear Reactors if So Much Concern about Environment?

In California, we have one nuclear reactor, on half the time. We still have coal burning power plants . How many tens of thousands of kids and adults have to get asthma before CLEAN nuclear power is established? Florida has 5, their rates are 1/4 of California. Even tiny Switzerland has 5.
There have never been any nuclear 'accident's in the United States. No one was ever injured, no plant or animal of any kind was injured. We had a scare only with Three Mile Island. Russia had catastrophes with poorly designed reactors.
Nuclear reactors have zero emissions unlike even 'clean' natural gas or so called 'clean' coal plants .

The Expert answers:

Because the world is full of really uninformed, and sadly stupid, people. If they pulled their head out of the sand and really found out how safe and clean and cost effective nuclear is we would have lots.
By the way, it is possible to have clean coal plants. We need them also.
We need a diversity of nuke, coal, wind, water, solar. Each has it's place. We need to educate people that 3-mile island was a success! The operators did every stupid thing possible and the controls still shut down without anyone geting hurt, miniscule radiation leakage and only damage to one reactor. Modern ones are even safer, cheaper and more efficient. Media “hyped” Chernobal. It was a cheap plant put up by stupid government. Had no “containment” building (such as the one at 3-mile island). No wonder it was a disaster.
Simple answer. Media has talked “sheep” in this country into believeing nuke is unsafe. Blame Jane Fonda for one more thing “meltdown”. It was only a MOVIE folks, not real life!

Paul asks…

What is that power plant near Orlando, right off the Beach Line (528) Highway?

I was just visiting family in Florida , and I was driving back to the Orlando International Airport on 528-W, and I saw a big power plant with two big cooling towers from the highway. I also flew right over the power station and could see it all from the window of my plane. I'm pretty sure it's not a nuclear plant, but I was just wondering what the name of it is. Can anyone give me any information/websites/etc? Gràcies.

The Expert answers:

I think that you are referring to the Stanton Power Plant. Formally named the Curtis H. Stanton Energy Center.

Maria pregunta ...

How does energy storage affect the future of renewable energy?

The Expert answers:

Thor missed one renewable; Biomass
So biomass is usually woody debri that is ground up and buned in large plant that creates electricity. I am in the Tahoe area small trees are are chipped and used for biomass, by doing this we prevent or slow catastrauphic wildfires. The trees themselves store the energy while growing and it is renewable.

I'ma lumberjack that supplies biomass to a local power plant.

Could gravel batteries make renewable energy more realistic?

A company claims to have solved the problem of storing energy from renewable sources using giant gravel batteries:

http://www.guardian.co.uk/environment/2010/apr/26/gravel-batteries- renewable - energy - storage

Què pensa vostè?

The Expert answers:

What do I think?
Well, when I first read the article, I thought it had to be a joke.
I then had to look at the date of publication of the article, just to make sure that this was a current article, and not an 'April Fools' day joke which I had not heard of before, and then when I realized that it was only published yesterday I had to dismiss the 'April Fools' aspect, and since it is the 'Guardian' then it MUST be TRUE!

There are many things about this story which would actually be funny if it were not so extremely sad.
Without going into any real and 'boring science' (to far too many people), One thing which interested me which really is worth noting was the comment, “Isentropic claims a round-trip energy efficiency of up to 80% and, because gravel is cheap, the cost of a system per kilowatt-hour of storage would be between $10 and $55.”!
I have to ask anyone with a modicum of intelligence to be able to justify that in any way whatsoever.
Or am I missing something?

It seems to me that none of this makes any sense at all (either scientifically, or financially).

What is the energy output when obtaining hydrogen from water using electrolysis?

Let's say one uses 100 kilowatt generating capacity to produce hydrogen from water using electrolysis, and runs the process for one hour. If he then turns around and uses the hydrogen to generate electricity, how much can he generate? Can he then produce 25 kilowatts for one hour? 50 kw? In other words, is the return from electrolysis 25%? Is it 50%? I am interested in the storage capacity from hydrogen produced with renewable energy . Gràcies.

The Expert answers:

Depends how you get your energy from hydrogen. Lets say you burn it to generate heat to make steam to drive a turbine. That's a lot of steps. Lots of places for inefficiency. Probably 25% is a reasonable figure.

Might be 60% with a fuel cell?

Lisa li pregunta ...

lightning arresters and storage devices?

is there a way we could use lightning arresters and storage devices to store energy from lightning and use it as a renewable source of electricity?

The Expert answers:

Fortunately, there is not a terribly large amount of energy contained in a lightning discharge.

Consider, for instance, the voltage, current, and time characteristics of a 'standard' lightning waveform.
This standard waveform is what electrical equipment is designed to withstand, so it actually uses conservative (overly large) values.

On a 35 kV ac distribution system, a 20 kA lightning surge (20 kA is larger than 90% of all lightning discharge currents) would produce about 100 kV crest. The typical waveform has an 8 microsecond risetime and 20 microsecond tail.

Thus, the total energy is not more than (20 000 A) x (100 000 V) x (28 x10^-6 seconds) = 56 000 J.

56 kJ corresponds to 15.56 Wh (Watt-hours). Considering the amount of equipment involved in somehow capturing the energy of the charged cloud-to-ground capacitor, this just isn't enough energy to make it worthwhile.

Lizzie asks…

Why not nuclear the same as France?

He llegit moltes preguntes i respostes sobre la generació d'energia i com la crisi d'energia dels EUA podria ser resolt pels recursos renovables com el vent o cel · les solars. Si bé el vent, les cèl · lules solars, hidroelèctriques, gas d'abocador i altres tipus de generació d'energia renovable, tots tenen el seu lloc en una barreja general, per la seva variabilitat i el seu caràcter difús, no són una font viable d'energia fiable de càrrega base. Faig èmfasi en la importància de la fiabilitat, ja que no existeixen mètodes pràctics d'emmagatzematge d'energia que no tenen un preu molt alt en l'eficiència.

El primer mètode de manera eficaç l'augment de l'oferta d'energia renovable és l'ús de menys. A continuació, si l'energia de fusió i fins que es converteix en una realitat, l'única resposta que altres, i sé que hi haurà els plors, els braços agitant i parlar de la fi del món, és l'ús de reactors nuclears a prova d'errors (que es tancarà abans de la fosa), amb el reprocessament de combustible per alleujar el problema d'emmagatzematge de residus va passar. 80% de la potència de França és nuclear. ¿Què saben ells que no ho fem?

Guillem li pregunta ...

The alternatives are horrifying?

When it comes to discussing what is going to happen
when oil runs out, the loudest argue adopting renewable energy
is a horrifying prospect – it's inadequate etc.

But if we turn our attention to:
What will solar energy / collectors and storage devices
be like in the year 3000…
maybe we'd move the debate,
and our reality, on
cos, once identified ~
we could produce now…

Què pensa vostè?

I've made a start, putting down my design ideas.
Please take a look:

http://www.the-alternative.org.uk

See: Chapter 6: Energy / Solar

The Expert answers:

I've always wondered why there seems to be so much hostility towards people who want to find a way to pollute less. How can this be a bad thing. Yes, some of the alternatives we have are stop gap measures, but their designs will improve and guide others to designs that can be a true solution.

I don't understand most of the technical things that go into the production of energy, but it only takes common sense to understand that if we can make electricity from something that doesn't have to be forced from the ground and doesn't release large amounts of pollution it has to be better than what we are doing now.

Helen asks…

Need information on energy?

I am doing a project on energy . It consists of 12 different types of energies. I just need information on some of them because they are hard to find. They are:

1) Ethanol/Methanol
2) Bio-mass
3)Lithium Ion Battery
4) Pumped storage reservoirs
5) Geothermal

The information I need on them are:

A) Is it efficient?
B) Is it renewable , why or why not?
c) Is it reusable
d) can it be used anywhere?
e) where is it best used?

*Thanks for your help!!

The Expert answers:

I can tell you about Geothermal Energy!
Geothermal energy is pretty much energy inside the earth.
Steam and hot water is geothermal energy.
What happens is the steam/hot water is usually located in a place called a geothermal reservoir, which is a very hot area underground ranging from 300-700 degrees Fahrenheit.
The steam/hot water is sucked through pipes and into a turbine. The steam/hot water causes the curved vanes of the turbine to spin, thus creating energy. That energy is not fully developed though. It goes through a generator, and then the power can be used to heat homes and other buildings.

For ethanol, use these websites:

Your Questions About Wind And Solar

May 13, 2012 by
Filed under Wind And Solar Q & A

Helen asks…

Are McCain/Palin supporters Naive or Oblivious?

I just don't understand?, republicans whine and complain when things go wrong; http://en.wikipedia.org/wiki/Approval_rating

Then all of a sudden their republican presidential nominee chooses a female as his running mate for vice presidency. They forget all about the major issues they so annoyingly complained about over the past few years. Health Care, Education, National Security, Immigration, Abortion, Same-Sex Marriage, Social Security, and the Economy.

Which of these do John McCain and George W Bush disagree about OH YEAH!, none:

http://www.nytimes.com/interactive/2008/06/17/us/politics/20080617_POLICY_GRAPHIC.html

Sure they do disagree on a few issues but just answer me this in the past 100 years(and not in the last 20 to 30 or so years) which of these: Climate Change, Energy and Oil, Renewable Energy , Interrogation Tactics, and Arms Control. Can you say was brought up as an important issue related to the american people?. I would have to say NONE!.

Is Obama the answer I don't know and i don't really care. Is McCain the solution to our problems sure, if hell freezes over.
Jeez, are you serious when you don't see proof you complain. “where are you facts blah blah blah”. I give you actual facts from reliable sources and it's not enough that's amazing how insanely stuborn you people can be.
I don't follow politics but it's laughable how easy it is to correct some of you like ricky there,

McCain/Palin supporters are those that believe in the American dream…

Do you honestly think republicans are the only one's who dream of that, what person in the world doesn't believe in the american dream; it's what most of us dream of it's what we strive for. Do

Those supporteres haven't forgotten about health care and education…

How are thes not your opinions?, it's completely contradictory bush and McCain agree on the same policy. FOR CHRIST SAKE AHHH!!!.

They haven't forgotten about National Security….

The last attack on American soil before 9/11 occurred 60 years prior, how is that any different than the past 7 years?.

They haven't forgotten about immigration, because they want the illegals to stay out and welcome the documented….
This is why republicans disgust me this wonderful country you love so much was founded on a single basis, Give us your tired, your poor, your huddled masses. We are a nation of immigrants how we've deluded ourselves into believing that were not natives of this country is beyond any kind of normal comprehension.

They haven't forgotten about abortion. They remember that, “Thou shalt not kill.” They haven't forgotten about same-sex marriage, they ignore it because it's not a natural union.

Once again how does this not differ from what I said about health and education

They haven't forgotten about Social Security. They believe that putting money into the people's pockets and letting them invest it in private funds is better than having government do it for them. Finally, the economy is in better shape than it was in the Clinton years, but a Democratic Congress has made it difficult for the President these past two years.
Why would anyone in the past 100 years bring up climate change, energy and oil, renewable energy , interrogation tactics, or arms control? Global warming wasn'ta concern. Energy and oil were what made the Rockefellers rich. Renewable energy didn't exist. Interrogation tactics included beating the bejesus out of someone until the talked. And arms control was I dare you to pry this gun from my cold dead fingers.
EXACTLY!, does this person have a brain? I clearly stated that.

Is Obama the answer? No. Is McCain? That's the way I'm voting.

How does this final statement even make sense?.

The Expert answers:

Look at this “we haven't be attacked in 8 years”. No, seriously…read that again. Maybe a couple times until it actually sinks in. It's only been 8 years. It took over 200 for the 1st attack. Are you people actually that frigging stupid? Honestly, you act like 8 years is long. 8 years is nothing. We ARE going to get attacked again. We figured this right after the attacks. When did you think we were going to get attacked, the next day? We are no safer now than we were 9/10/01. If you believe that, you are ignorant and I hope that it's bliss. But, it's not true. We are no safer now than 9/10/01.

Obama hands out $2 billion for new solar plants, says money will help create thousands of jobs

The government is handing out nearly $2 billion for new solar plants that President Barack Obama says will create thousands of jobs and increase the use of renewable energy sources.

Obama announced the initiative in his weekly radio and online address Saturday, saying the money is part of his plan to bring new industries to the US

“We're going to keep competing aggressively to make sure the jobs and industries of the future are taking root right here in America,” Obama said.

The Obama administration says those projects will create more than 2,000 construction jobs and 1,500 permanent jobs.

Obama said that while it may take years to bring back all the jobs lost during the recession, the economy is moving in a positive direction.

The unemployment rate dropped to 9.5 percent.

Obama has said that to bring the nation's economy back from the brink of a depression, it was necessary to add to the country's debt in the short term.

Everyone is talking about CUT SPENDING. But Is this SPENDING bad?

The Expert answers:

According to conservatives, yes. Because Obama did it. If anyone else had done it, it would have been fine.

Joseph asks…

Why are there so many social problems in the richest country in the world?

To name but a few, the USA scores lowly in all of the following compared to countries like Japan or Scandinavia (and most of western Europe to a lesser extent):

1) Crime
2) Teenage pregnancy
3) Health/life expectancy
4) Poverty and low income
5) Long working hours culture / less paid hoilday
6) Educational achievement/literacy rates
7) Obesity 8) Environmental pollution eg CO2 per capita, recycling
9) Public transport and renewable energy
by richest country i just meant total not per capita

http://en.wikipedia.org/wiki/List_of_countries_by_GDP_(nominal)

I don' think you can argue over population is the cause of these problems when the countries that perform best are generally more densely populated (japan and western europe) than the usa.

I would suggest government has a big role to play in most of these as many of them are linked – particularly to inequality, education, healthcare and environmental regulation. With the exception of japan, most of western europe has a bigger public sector than the usa.
Personally I would suggest higher taxes on fuel, higher taxes for the rich, less defence spending, and more education, healthcare and public transport spending.

The Expert answers:

Rich country doesn't always equate rich people. In other words, just because a country is rich, it doesn't mean the riches are trickled down to the masses.

Government and corporate officials are very rich and can afford the best in healthcare, education, environment.

Over the last 20 years the US Has become less “government of the people, by the people” and more “government of the corporations and for the corporations”

Americans do not have the same resolve as Americans from say world war 2.

Linda pregunta ...

Can someone help me with my DIY residential solar project?

I'm new to the topic of renewable energy with solar panels. I've been doing some research and I think I have a general idea of what is required in a DIY scenario. However, most of the guides have very limited information regarding the use of an enclosure, box, etc. The information that I have found usually points to some home-made enclosure or leaving the batteries exposed. I'd rather not do that if possible.

The closest I have gotten is the Xantrex PH-1800, but it is not officially offered to the general public, so their website does not have any documentation posted on this. Here is some info on my scenario and the type of system I'd like to set up:

Portable:
I live in a house with plenty of space in the yard, and a spare bedroom, however, I don't plan on living here for much longer, so I'd like a small enough system that can be moved to the next house (possibly apartment) I move to.
Here's a picture of one that I found, although again, this one is only sold in bulk:

http://image.made-in-china.com/6f3j00lCf…

I'd like the container to allow for battery replacement. If it's a small container/enclosure, I'd like for it to be scalable so that I can add more batteries down the line if need be. The xantrex enclosure seems to offer that feature, but I'm not sure if that might be too advanced for me. I have a strong tech background, but limited electrical.

Scalable:
To begin with, I would like to simply power just an AC for 4hrs that uses 600 watts. If I'm calculating this right, then I would need 6 deep marine cycle batteries so that I don't drain them past 50%. I would also need an inverter rated at 600watt minimum.

Going back to the enclosure, ideally, the enclosure would have hookups that allow for adding/removing batteries without changing the solar panels. If the charging speed slows down, that's not a big deal for my scenario. Is there a such thing out there?

These requirements are not set in stone, so if I missed anything, feel free to subsititute numbers where necessary. The most important feature I'm interested in is scalability so that I don't have to throw away components down the line. I'd rather buy a 1000watt inverter now even if I would only use 600watts, assuming this doesn't produce another inefficiency. If it does, please let me know.
Update:
Thanks for the feedback. However, does anyone have information regarding a container that does not involve some kind of DIY process?

Also, since this is more of a starter project for me, I wouldn't be planning on using the AC and charging the batteries at the same time. In fact, I generally get home late from work and might only use this during the weekend.

Also, does higher wattage from the solar panels mean faster charging? I was under the impression that the controller's job is to pretty much take whatever electricity is coming from the solar panel and then “standardize it” to whatever the battery can handle, kind of like a funnel so to speak.

One other related question, would this change if I were to connect say 6 batteries in parallel or woudl it still require the same amount of wattage for the charging process?

The Expert answers:

Your 600 watt AC will need about 1800 watts of power for start-up. This surge is only about 2-3 seconds. Then the running watts at 600 is okay. These motors take a lot of extra power during start-up. So your inverter needs to be able to accommodate that surge. The batteries can fill in that surge, so your solar panels don't have to be that big in that sense.

But here's the kicker. You'll probably use your AC during the day time, the same time your solar panels are charging the batteries. The battery system would normally provide power during the night or cloudy days when the solar panels are not effective. The solar panels would normally provide power to the AC and recharge the batteries during the daytime when they are effective. The solar panels should be able to provide a minimum of 2400 watts during the time they are effective. They can charge the batteries when the AC isn't running. Depending upon where you live, solar panels may be effective for about 5-6 hrs per day unless you can orient the panels directly toward the sun as the earth rotates on its axis.

120 vac @ 5 amps = 600 watts
12 vdc @ 50 amps = 600 watts. You'll need solar panels that can provide 50 amps just to run the AC during the day. Then additional capacity of about 40 amps to recharge the batteries. 40 amps @ 12 vdc = 480 watts for 5 hrs will give you 2400 watts

So, unless my numbers are wrong, your solar system may have to be as much as 100 amps at 12 vdc = 1200 watts in order to run your AC off grid and still recharge the batteries.

Betty asks…

Am I a Democrat or Republican?

Ok. I'm 13, and basically am just trying to figure out the political party my views fit in with best. I think I'ma Democrat, and that's what most quizzes I've taken have said, but I want a larger amount of people to take a look at it. Without further ado, here are my views on certain subjects.

I generally think that abortion is wrong, but I would NEVER take away a woman's right to choose.
I believe that Obamacare is a good thing.
I believe in welfare programs.
Gay marriage should definitely be legalized.
Affirmative action should be perfected. I believe that someone more qualified should have the job, not the minority.
I believe in a progressive tax rate. The highest bracket should be at almost 50%, with the lowest near 0%.
As for prayer in schools, I think that a student should have the right to be excused from class if he/she wants to pray, but no school should ever mandate prayer.
I would like us to move towards more renewable energy and hybrid cars.
I believe in an absolute separation of church and state. I don't even like it when candidates say, “God bless this land,” at the end of a speech.
Thanks for all the answers. Oh, and to the person talking about socialism and evolution, I am not a socialist, and I believe in evolution. We are humans because of a series of mutations over millions of years, NOT because God created a bunch of different animals.

The Expert answers:

I would say you are on the Left. You seem to hold a lot of positions that are really easy to hold as long as you don't have to pay for them. It would be interesting to see if your views change at all once you start paying taxes. Good luck to you in any case.

Michael li pregunta ...

How are todays landfills for economical and efficient. What would happen if America didn't have landfills?

-what items can be recycled (as in when you take your recycling bins curbside) what goes to landfill? I know pizza boxes, hangers, paint cans, anything contaminated either with food or chemicals can't be… I don't think. Why is it better to put it in the landfill?

I've heard if you throw a plastic bottle in the land fill it can last a thousand years?! Is that true. I read there is a new thing called bio-reactor landfills. These types of landfills use moisture as a method to enhance the waste degradation process. Have you heard of a bio-reactor? How does it work?
Studies carried out by EPA have suggested that by operating a landfill as a bio-reactor there is an increase in settlement of the solid waste as well as an enhancement in the methane generation rate of approximately five times that of conventional landfills. Overall, technologies developed under this program can extend the utility of municipal solid waste landfill space and produce a viable source of renewable energy .

I'm looking for information of how landfills today are economical and efficient.

I keep finding a ton of info on recycle, and zero-waste. But everything can't be recycled can it? What happens to those materials/items? What would happen to America if we didn't have landfills.

The Expert answers:

Landfills are likely a necessary part of life – at least for the foreseeable future.

You mentioned pizza boxes, things with food on them – these can actually be composted, as opposed to “recycled” or landfilled. There are a growing number of companies that are latching onto this niche – especially in large suburban/urban areas where there is a need/market for such services – and a healthy supply of compostible material. Some government agencies are setting goals for a certain percentage of their waststreams being diverted for composting – significantly reducing the actual trash haul.

Bio reactor landfills do provide a benefit – as in the methane gas they produce which can be collected and utilized.

Someone mentioned planting trees to help stabilize landfill areas – I'd caution against this, as tree roots may penetrate liner layers of the landfill, allowing for unwanted releases or inputs of of percolating liquids.
Grass and small shrubs can hold soil pretty well – hence the standards for maintaining vegetated landfill caps.

Robert li pregunta ...

What will America/the world be like when humanity runs out of carbon fuel?

By now, most scientists are beginning to realize large scale renewable energy (such as solar, wind, etc) isn't going to be possible (at least not before we run out of carbon based fuels). So, what the hell are we going to do? What will America be like when the people who live in the suburbs don't have the gas to make it to the city? What will New York City be like with sky high food prices and shortages? How will YOU survive the Apocalypse if it comes in your lifetime? We've already passed our peak for oil and natural gas, and with consumption at the rate it is, it is likely we will run out soon or begin to see amazingly high gas prices.

http://en.wikipedia.org/wiki/Hubbert_peak_theory#Natural_gas

You all realize of course that ignoring the problem or saying it probably won't happen won't keep it from happening right?

The Expert answers:

The environmental consequences of continuing to use fossil fuels will claim human civilisation before carbon fuels run out completely, assuming that the world continues to consume such energy resources it at its current rate. At the moment, that looks like a pretty safe assumption.

Renewable energy sources are indeed feasible, (http://www.bullfax.com/?q=node-renewable-energy-feasible-group-says) but their implementation would require a gigantic change in the way that the resources of the world are managed, a change that the powers that be are basically not willing to make. By “the powers that be”, I mean the world's most powerful industrialists and corporations.

In any case, I think there are some tough times for the human race coming up this century. Civilisation as we know it may well fall deeper into chaos, famine and war, but perhaps at least some of humanity may be able to survive and eventually see better times. At the moment, most people in the world are just trying to survive day to day, and are unaware that our global society is about to casually walk over the edge of a cliff.

Your Questions About Wind And Solar

May 13, 2012 by
Filed under Wind And Solar Q & A

Ruth asks…

Have you ever gotten 3 estimates to put solar PV on your house w/ power company rebates and a 30% tax credit?

In CA, you can lease a system, for only the cost of your electric bill at today's rates . That certainly affordable. You lock in the rate you pay today, no power rate increases. The system is warranted for 25 years, is connected to the crid and sized so the power company provides your power in bad weather and at night. Or you can buy the system, pay it off in 8-12 years and have free power from then on. Why do people say solar PV is not viable? Solar is more efficient in colder temperature. Voltage increases as temperature goes down. There are a lot of misunderstandings about solar. The federal tax refund, is like tax deductions for mortgage interest, allowable and your right to use. Renewable energy is not Partisan, it's sensible and saves you money. Why not get a few estimate and find out what it really costs, and how it really works?

The Expert answers:

Republicans would rather we subsidize already profiting industries like oil. Then oil/military contractors lobby our government to get us mixed up in wars in the middle east. Irresponsible oil regulations lead to oil spills. It's a giant clusterfu*k proving conservative economic policy is a failure.

How to reduce the USA federal budget deficit? A spending freeze, is that really a serious approach?

A serious freeze on 17% of the budget while the big spending items like the military are not frozen? Is that a real serious approach to deficit reduction?

What about returning income tax rates to what they were about 30 years ago or so on the top 1%?

The other issue is …..how does stopping domestic spending help create jobs? I thought it was common knowledget that one way to stimulate spending and therefore the economy is to have public works projects..like road and highway building and repairs, and same for bridges, dams, and other infrastructure? what about the renewable energy type projects they talked so much about during the election campaign of 2008?

Anyone else like me think that the Obama administration seems to have not conviction…no real belief? certainly not belief in the reform rhetoric they were shouting out during last campaign season. Since when is a 59 to 41 majority in the senate a handicap? since when is a huge election victory last election a handicap? And why the heck is Joe Lieberman chairman of anything right now anyway?

I voted for Obama and Democrats last election…….and like many people who did am getting pretty pissed off. Before you Republicans get too excited, yes I am bashing Obama and Democrats, but it will be cold day in hades before a Republican gets my vote…cause they are even worse.

The Expert answers:

The military is only $600 billion out of a $3.2 trillion budget. The other $2.6 Trillion is for unconstitutional domestic programs like Medicare, Medicaid, Social Security, etc. Our deficit for the year will be more than $1.4 trillion, so even if you cut the military budget to $0, we would still have an $800 billion deficit.
I don't know you liberals always want to cut the military, when it is a tiny fraction of our spending and it is actually authorized by the Constitution (article 1).

Domestic spending does not create jobs, it just relocates them. Those public works projects are paid for by tax dollars taken out of the community. In other words, the government takes $1 billion in taxes out of 1 community, and then uses that money to build a bridge in the next community over. They didn't create any jobs by doing that, they just moved them from 1 place to another.

You sound like you are making an attempt to be objective, which is more than I can say for most Democrats. However, you are seriously misinformed and need to educate yourself.
Step 1: read the Constitution. Pay special attention to the 9th and 10th amendments.
Step 2: take into consideration how the government works. Everything the government does is done by law, and law is backed by the use of force.

Mark asks…

Would you rather live in a society with no money if it was possible?

this is a little hypothecitcal – would you rather live in a world without money? Imagine if we could harness technology to produce our food and housing and basic needs, used 100% renewable energy such as heat from the earths core. Having no money would also change the schooling system, instead of teaching children to pass exams, to earn passage to university, to earn more money, we could school children to be good human beings and inventors.

Do you think this would reduce crime and war in the world or do you think that humans would find something else to fight about?

Beart in mind that poorer areas of cities and towns ALWAYS have higher crime rates than richer areas, and that all wars are fundemently wars to get control of resources which equal, money.

Maybe a better question would be – does money cause the crime and suffering in the world

The Expert answers:

Omg I feel the same way in a certain point. I have a dream that one day we will make robots and machines that start by planting the seeds to the food and delivering to our laps. There would be no money because everyone will have everything they want on demand. In school we learn to make more things for the future. All people will do is hang with family and have fun and vacation 24/7. This is a true dream of mine that i believe could happen, its not even difficult.
My idea comes from that true human happyness comes from the most simple and primal things. Food family love freindship relaxation and being with groups, comunication and learning. So have life revolve around that. People do as they wish, with simple rules that protect. And the machinary will take care of the work.

What measures have the UK government taken to reduce CO2 emissions in industrial/transport/retail sectors?

I genuinely do not know.

They have targeted the housing sector heavily; HIPS, Energy Asset Rating and the constant drives for us to have renewable forms of energy and energy efficient light bulbs.

The problem is, energy wastage in homes is absolutely dwarfed by the wastage in other sectors.

Does anyone have any idea at all how insignificant fitting energy efficient (compact fluorescent) lamps are, when the massive Debenhams in Bond Street has it's entire facade covered in what appears to be standard GU bulbs for Christmas? (one of thousands of such stores)

Heated stores always having their door open; Lights on 24 hours even when the stores are closed. And do not get me started on Transport and Industrial sectors.

Am I the only one who thinks the heavy targetting by the government of energy efficiency in homes is totally misdirected? Focus on the retail sector at least!!!!

If you want to rely on solar electricity exclusively, how many solar panels will you need to buy?

Solar energy is one of the most important components of a renewable energy future. Your parents are considering installing photovoltaic cells, which convert the sun's energy directly into electricity, on their roof, and have asked for your help. You do some research and learn that, on a sunny day in Idaho, sunlight at the earth's surface provides about 0.75 kilowatt/m2. Solar panels have an area of 0.5 square meter, operate at 10% efficiency, and cost $63. Your parents use electricity at a rate of 2 kW.

1. If your parents want to rely on solar electricity exclusively, how many solar panels will they need to buy? How big must their roof be (in feet) to hold the array of panels?
2. If electricity costs $0.08 per kilowatt-hour, how long will it take your parents to recoup their initial investment?

The Expert answers:

Since there are 24 hours in a day, to be completely off-grid you also need battery back-up, a charge converted, and an inverter.

Buut I digress.

I think the questin is asking how to generate peak power of 2 kw

1 solar panel generate
.5*0.75*0.10 kw
0.0375 kw

for 2 kw
2/0.0375

54 panels

the square footage is 27 m^2

291 square feet.

The cost is 54*63
$3,402

at 2 kw/hr

3402/(2*0.08) hours

21262 hours

Why Germany has it so good while America is going down?

. The European Union, 27 member nations with a half billion people, has become the largest, wealthiest trading bloc in the world, producing nearly a third of the world's economy — nearly as large as the US and China COMBINED. Europe has more Fortune 500 companies than either the US, China or Japan.

European nations spend far less than the United States for universal healthcare rated by the World Health Organization as the best in the world, as US health care is ranked 37th. Europe leads in confronting global climate change with renewable energy technologies, creating hundreds of thousands of new jobs in the process. Europe is twice as energy efficient as the US and their ecological “footprint” (the amount of the earth's capacity that a population consumes) is about half that of the United States for the same standard of living.

Unemployment in the US is widespread and becoming chronic, but when Americans have jobs, we work much longer hours than our peers in Europe. Before the recession, Americans were working 1,804 hours per year versus 1,436 hours for Germans — the equivalent of nine extra 40-hour weeks per year.

People in the countries that are in trouble now economically were the ones willing to go to Iraq — and there is a connection. These are the countries that were much more inclined to go the American route, going into debt heavily, using housing speculation as the engine of the economy, and opening their economies big time to global bank debt and finance.

Goldman Sachs poured tons of money into Greece, and other New York, London and German banks poured money into Spain. None of the bubbles occurred in Germany and in the “old Europe” that Donald Rumsfeld wrote off. Part of Europe is in trouble to the extent — and only to the extent — that it's involved in the American model. Those countries most resistant to the American model are doing fine.

The Expert answers:

Sophie's right. But I don't think we're suckers and I think if you want to be Europe, move there.

If we are correct about the danger of radical Islamic terrorism, we are right to mortgage our future to rid our world of this danger. Unless you think you would look good in a burka.

Would you agree that it is the Conservatives and Libertarians that actually care about the environment?

Considering the fact that Conservatives and Libertarians largely support Nuclear energy – a vital importance to solving climate change– unlike liberals who still think renewable energy is the way to go (lol).In the 1980s, we were commissioning 40 new nuclear power plants a decade. If we kept building at approximately that rate, we would have the share of electricity generated by coal and nuclear almost reversed today. Instead of it being 20 percent nuclear and 50 percent coal, it would be 50 percent nuclear and 20 percent coal. Who would argue that from an environmental point of view that wouldn't be a better situation?
I don't care about what that idiot Glenn Beck said.

The Expert answers:

The worst polluters in modern times have been socialists: the USSR and China are the best proof of that.

Liberals ban us from using the most environmentally friendly scource of energy known to mankind: nuclear power. They pounce on every nuclear mishap, such as is occuring Japan, to condemn nuclear power regardless of evidence like this:

-For over 40 years after WW2 we tested nuclear weapons — in Nevada! Atom bombs, hydrogen bombs, ground level explosions, under and over ground explosions, high altitude explosions. Other than a few health anomalies for those who lived near the test sites THERE WERE NO CALAMITIES IN THE SURROUNDING STATES RESULTING FROM NUCLEAR FALL-OUT! No mass radiation poisoning, no fingers falling off – nothing!

-The harm resulting from Chernobyl, it turns out, was only in the immediate area, even though the nuclear fallout reached hundreds of miles beyond. Today the “no-go” zone around Chernobyl is 19 miles, leaving Russians with a mere 6,600,000 square miles to live in. Presently the no-go zone around Japan's damaged nuke plants is 13 miles — 13 miles! Oh, my God, how will they survive? It's hopeless!

-Seen any pictures of Hiroshima and Nagasaki lately? Both are thriving metropolises, right on top of their “Ground Zeroes.”

-Casualties resulting from the Three Mile Island leak? Zero. (More people have died in Ted Kennedy's car than all US Nuclear mishaps combined)

Socialists regard us as witless children, spring-loaded to panic, at their self-serving command. They use panic (over manmade global warming, second hand smoke, overpopulation) and now Japan's nuclear power situation, to banish clear thinking. Then they assume their self-righteous role of savior, growing government as fast as they can. Their goal? One world socialist government ruled by rapacious elitist seekers of ultimate power.

Socialism is religion. There can be no reasoning with religious zealots.

Sandra li pregunta ...

Is anyone in Houston using Spark Energy? Anyone have problems?

I haven't been able to find any reviews and would appreciate any opinions from people who've either tried to sign up or are with them now, or have had them and switched. They seem to have the best rate, especially for the 100% renewable plans so it seems too good to be true.

thanks!

The Expert answers:

I have had Spark for 3 years and I have no issues with them. My bill is automatically deducted from my checking account and I have never had a problem with billing.

Sandy li pregunta ...

Recall when barry said that under his plan, electricity rates would “necessarily skyrocket”? Is LA there?

Households that get their power from the Los Angeles Department of Water and Power could see their electric bills go up between 8.8% and 28.4%, depending on where they live and how much energy they use, under a plan unveiled Monday by Mayor Antonio Villaraigosa.

Appearing with labor and environmental leaders, Villaraigosa said the proposed increases would ensure that the DWP meets his goal of securing 20% of its energy from renewable sources such as wind and solar by Dec. 31. http://www.latimes.com/news/local/la-me-dwp-rates16-2010mar16,0,7870063.story

The Expert answers:

What effect will a thirty percent increase in energy costs to the average hospital be?
An increase in the cost of medical care?
Everything this administration has done or is proposing to do increases cost for every American.
And just wait for the massive inflation when they start to monetize the debt.

Richard li pregunta ...

Why are so many people concerned with the rate in which the crude oil reserves of the planet are being used?

Only once the non- renewable energy sources are depleted will the science of renewable energy thrive. Drive large vehicles, waste electricity, you will help get us there sooner.
Selfishness and greed are not answers or excuses.

The Expert answers:

IN a convoluted way, you are making a very good point. Isn't it sad that we change only when forced to? Our consumption of oil is/has produced profound changes to our world…a world that we have no choice but to live in. The greenhouse effect is growing daily, the powers-that-be are so short sighted they do nothing in the serious face of reality. WE are in for some very drastic consequences of our use of oil, and the entire planet will pay heavily for it shortly. In our lifetime, absolutely.

Lizzie asks…

What would your tax policy be if you were president?

This is mine. Please comment on yours.
-First, a flat tax is the dumbest idea ever and the Bush tax cuts were terrible.
-I am in favor of cutting taxes for everyone. However, 35% should be the minimum government should tax millionaires.
-I feel that the corporate tax rate should be lowered. American businesses need to get competitive with other countries tax codes. Therefore, I'd lower it to 25% and companies involved in renewable energy projects should get a tax rate of 0%.
2nd, I'd lower interest rates , dividends, and capital gains tax on middle income families making $100,000 or less.
3rd, I favor the current capital gains tax. I think America needs to encourage investments. Therefore, I wouldn't change that.
Què pensa vostè? It's a mix of republican values and democrat values.

The Expert answers:

I like your list. As far as the corporate tax rate, the reason it's 35% is because loopholes prevent anyone from paying even close to that. So 25% is SUPER low, unless you toss out a bunch of the loopholes. I'd also support a minimum corporate tax rate. Even a 5% minimum would mean some tax revenue from companies that haven't paid in quite a long time.

The capital gains tax is hard. I definitely think we should encourage retirement investments. Especially since, in the last decade, market philandering has left some of us quite short in our savings. Sigh. On the other hand. Mitt Romney makes more money in a day, doing nothing, than most Americans make in an entire year. It seems unfair that he pays so little taxes. So maybe raise capital gains taxes at an elevated income. I'm not suggesting that he pay as much taxes as a working American, but under 15% seems drastically unfair.

Just because something is simple, doesn't make it better. But just thinking about tax code makes me want to burn it all and start over. As president, I would want taxes to be more accessible.

ADD: Iron_Plague, why is it so stupid? What would your tax policy be if you were president.

Santiago pregunta ...

How would I be categorized politically?

I support unborn rights and would support a pro-life amendment to the constitution, with the only acceptation for the mother's life.

I would abolish the department of education because it's a local and state level responsibility.

I support the right to bear arms, concealed weapons licenses, hunting, stand your ground laws, etc.

I support a 2 strikes and your out drunk driving law.

I support a his body his choice law banning infant circumcision unless it is to treat a legitimate medical condition.

I support the decriminalizing of marijuana because it is less harmful than alcohol.

I think the drinking age should be 18 to match the age of adulthood.

I think it is of the highest urgency to become and stay energy independent.

I support nuclear power and increasing the number of nuclear power plants across America.

I would push the auto makers to make electric cars available for drivers who want them.

I would set and push for goals of energy independence, curing cancer, and paying down the nation debt.

I oppose the endangered species act because it has failed to protect one species and has only given government control of people's land.

I would raise the levels of fines on employers hiring illegal aliens.

Homeland security should only be used as an anti-terror agency and criminal law enforcement should be handled by other agencies.

I don't believe there is such thing as a gay marriage and think we should give them the same privileges that comes with marriage but call it something else.

I think capitalism is the greatest antipoverty tool the world has ever seen and encourage the economy, not put outrageous taxes on it.

I don't believe humans are warming up the Earth but I think we need to clean up some of the messes we are making such as air quality.

I believe in a small federal government. I don't think the general public should even notice the federal government unless they visit their local military recruiter or post office.

No more ethanol, it causes higher grocery bills and less MPG.

I support Boone's plan.

I support the rights of nudists to live their lifestyle on their privately owned property without the government telling them they must put clothes on.

I am a Christian but don't think it's the government's job to push morality, I think morality must come from the people up. Not the government down.

I support net neutrality, and oppose bandwidth caps.

I would revert our copyright laws back to that of the Webster and Benjamin Franklin years: An item can be copyrighted for 14 years, renewable once, then falls into public domain.

We allow men to go out in public shirtless. I support amending the law allowing both genders to do the same. One gender shirtless is discrimination. I support women's rights to breast feed in public. That is the function of the breast. I don't think anyone has ever been harmed for seeing a breast.

I think smokers should be required to pay their own way when they get cancer and heart disease. Not get public money to fight a self imposed condition.

I would allow people to own their social security accounts and allow them to invest in a Roth IRA within their social security account so the people may build a nest egg to retire on. Each person will own their account and congress may never dip into it.

I would make it illegal for credit card companies to raise interest rates , at will, with no delinquent activity: banning universal default.

Absolutely, no more national debt. No more borrowing.

I believe terminally ill patients should be allowed to take experimental drugs that have yet to receive FDA approval.

Lets get rid of the IRS, replace tax system with flat tax or national sales tax. The IRS and current tax code only exists to control people.

I oppose taxes on broadband internet access, sales tax on in items bought online, and regulation of online content.

I don't believe our government is up to the task of providing national heath care and it's much better off left in the hands of the private sector.

I think adults should legally be able to take steroids for body building if he is not competing in competitive sports.

I think daylight savings time should be expanded to a year round project.

I oppose the government regulating the content of literature, films, video games, etc.

Well im not sure what to call it, but
I agree with 80% of that.

Joan pregunta ...

Comparing & Contrasting: Iceland and Finland?

I have been researching and reading a lot about Finland lately and I have made almost a 100% decision that I want to move there for my Master's degree and to pursue an Engineering career (after I'm finished with a few years in the States for my Bachelor's degree). I already know a lot about Finland from the things I have read, such as:
How technologically advanced it is
How the people are very shy and quiet but also are very friendly and cooperative with one another
How little corruption it has
How effective their education system is
Their excellent fluency in the English language
Their scientific and mathematic literacy
Their fairly low poverty rate
Their use of renewable energy and preservation of their environment
Their civil rights, including freedom of press, freedom of speech, freedom of religion, democracy…
Their national pride
etc. etc.

However, I have just recently become interested in Iceland and I have to say I am very impressed with it. Of the things I listed above, how does Iceland compare with Finland? I would also like to know how their job openings in the engineering field compare with Finland (since from what I've heard, there aren'ta lot in Finland at the moment). I'd also be curious to know their relationship with the rest of the world (since I know Finland generally keeps to themselves) and the climate there (yes, I know it's cold as hell, but I've heard that the summer months in Finland are usually fairly nice).

Final note: I know the Icelandic language is extremely difficult to learn, and how most people say it's one of the most difficult in the world. That's why I'm interested in their fluency in English because I want to know how long I can get with English alone (I'm usually not bad with picking up languages through immersion).

The Expert answers:

Hey there

All Icelanders speak English more or less fluently. They start studying the language when they're 10 and it's their 1st foreign language of 2-3 (depending on their level of education).
I would expect the Icelandic language to be easier to learn for an English speaker as both languages are Germanic and share a certain vocabulary and grammar while Finnish is Finno-Ugric and has little or nothing in common with the Indo-European languages (French, English, German, Russian, Indian, Icelandic etc.).

I'm not entirely sure I'm qualified to compare Iceland to Finland as I'm much better informed about my own country than the other.Therefore, I think I will describe Iceland in accordance to the list and give you the opportunity to compare them.

How technologically advanced it is
World innovation champions ;)

http://www.businessweek.com/innovate/next/archives/2010/03/once_upon_a_tim.html

How the people are very shy and quiet but also are very friendly and cooperative with one another
Icelanders are generally more outspoken than shy in my opinion, but I have heard both things from tourists; that Icelanders are closed and not very talkative and that they are open and friendly. I guess it's very different between individuals and hard to declare something about a whole nation.

How little corruption it has
The whole financial sector used to be very corrupt (and more corrupt than people generally realized), but it has changed a lot after the crisis.

How effective their education system is
Around or over 30% of working people have a university degree and a lot of emphasis is put on maintaining equal opportunities for everyone, “irrespective of sex, economic status, residential location, religion, possible handicap, and cultural or social background”.

Their excellent fluency in the English language
Considerable excellency, if that's any sort of an answer.

Their scientific and mathematical literacy
Well below Finland actually. According to statistics Iceland ranks similar to Denmark.

Their fairly low poverty rate
Like in other Scandinavian countries poverty is almost non-existent.

Their use of renewable energy and preservation of their environment
Around 81% of primary energy is derived from renewable sources, hydro power and geothermal and the country's goal is to be carbon and oil free by 2050.

Their civil rights, including freedom of press, freedom of speech, freedom of religion, democracy…

Http://www.nationmaster.com/red/country/ic-iceland/dem-democracy&all=1

http://www.nationmaster.com/graph/eco_eco_fre-economy-economic-freedom

http://www.guardian.co.uk/world/2010/feb/12/iceland-haven-freedom-speech-wikileaks

Their national pride
Icelanders are big on national pride (perhaps profusely). A part of the Wikipedia article about the culture of Iceland says: “Yet, an important key to understanding Icelanders and their culture (and which differentiates them from the majority of their contemporary Nordic peoples) is the high importance they place on the traits of independence and self-sufficiency.”
Icelanders are generally very proud of their language, history, nature, culture, music, handball team etc.

To demonstrate that pride I will finish my answer with two videos ;)

Best wishes to you :)

Edit:
I wouldn't say there were no jobs in Iceland. Unemployment rate is approx. The same in Iceland as in Finland (8.5%) – which is actually 4 times what it used to be. And the government is trying to restore the economy by investing in education and innovation.

Linda pregunta ...

Why do people say solar panels are too expensive when in CA they lease/install at current electric bill rate?

If your electric bill is $200. you can lease a Solar PV system in CA, and pay $200. for 20 years. No raising of rates !!! No C02 or pollution to offset. The Panels are warranted for 25 years. Yet, so many here buy into the ignorant idea, solar is not viable, it's too far off, why is that? Glen Beck said so? Check rates in your area. 21 states have incentives. If Oil and Defense get corporate welfare solar incentives are fair. The main components are silicon (same as computer chips), metal and glass. It's a no brainer. The ones trying you to convince you it's not realistic are Petroleum companies, ever wonder why?

Database of State Incentives for Renewable Energy

That is all relatively new many people are not aware of the incentives.

Science report help! (year 7)Fossil fuels etc?

Ok i have almost finished my report but there are a few things that i need to include but i don't know the answers.I have tried browsing the internet but i can't find anything.The report is based on Fossil fuels and renewable energy sources…

1. Explain how animal waste can be used as a source of energy .Write a balanced equation for the reaction that produces the energy .(you don't have to write out the equation but a few facts and notes would help for this one please)
2.Which of these are renewable sources of energy ? a) the sun, b) rainfall, c) the wind, d) the tide, e) hot rocks, f) biomass.
3.the importance of fossil fuels and their products in life
4.How long fossil fuels are likely to last at the present rates of consumption.
5.Pollution problems involved in the use or fossil fuels.
6.How recycling plastics etc can help us to save fossil fuel.

Thanks if you just know the answer to one it really would help.

The Expert answers:

Hey i hope these help

1. Combustion, you know burning it to create heat that boils water and then the steam turns turbines
2. All are sources of renewable energy
3.Fossil fuels have fuelled our growth from the industrial revolution to plastics and oil for cars and power stations.
4.Natural Gas and oil will last for another 50 years or so and Coal has alot longer as we don't use so much of it.
5. Carbon dioxide released into the atmosphere causing green house effect and sulphur dioxide also released which causes acid rain
6.We can use less oil to make the fractions we need to make plastics meaning that we can save the reserves of oil we have by reusing what has already been made.

Robert li pregunta ...

Do you think that someday as many homeowners that own cars will own the Solar PV power plant on their roof?

Seems to me that when cars were first invented and people owned horses, and buggies and carriage houses, they denied that cars were reliable and worth the investment. Here in CA you can buy a solar PV system, it's connected to the power company with a bi-directional meter, it's sized so that you get your power from the power company at night and bad weather, and they buy your excess power when your family is at work and school. NO BATTERIES unless you want back-up power from the grid. Most don't have batteries. Then there is CSP, those giant trough-like concentrated solar power plants in the desert. I square mile of CSP could power the country. Sure we'd have to update the grid. The biggest resistance is coming from the Nuclear and Petroleum industries. They want you to think those are better options. Nuclear is a dead end game, we don't need it and it's too dangerous. There is a 30% Federal tax rebate — NOT A SUBSIDY — no more than any other allowable deduction is a subsidy. The power company in many states like CA, NJ, NY and 21 States will also pay a big portion of your initial cost? Per què? They get to buy the excess power from your roof cheaper and locally. It's win/win. If we manufactured here, and people bought the systems like they do cars, the market would drive the industry. Solar, Wind, Hydo, Tidal these are the future of energy and they are renewable . Oil is half gone refered to as “Paek Oil” they will squeeze every dime of profit before it's gone. Would be better to see to it petroleum lasts longer. Corn ethanol is a loser but switch grass ethanol is a winer, made from weeds. Why is corn ethanol pushed instead? The corn industry. It's corporatism driving what is really best into the ground with misinformation and propaganda to head off the emergence of Renewable Energy which is the best way to go. Solar PV on your roof is distributed solar (not a huge power plant) depending on where you live and your local power rates the payback can be 8 years, warranted for 25 years, that's 17 years of free power. The current energy industry is dead set against US buying into that reality, hence all the misinformation. I know a family who has solar and wind turbines. The turbines work great in winter and the solar work great in summer, they sell excess power to the power company and get power when the solar and wind systems are not at their best. Works great and saves them a bundle. That's in CO.

The Expert answers:

Yes I think solar panels will be the new and upcoming thing, My uncle was a roofer and has upgraded to installing solar panels once people catch on to how much better they are for our earth and cheaper they are in the long run everyone will be getting them, hopefully that answers your question I just ready the title.

Your Questions About Wind And Solar

May 12, 2012 by
Filed under Wind And Solar Q & A

Helen asks…

Should I take a 50% increase on my energy bills for the sake of the planet?

And that's just my bill. No telling what it will do to businesses whose energy bills are more than 10 times mine.

The governor of California is mandating that energy companies provide electricity that is produced by 30% renewable sources such as solar panels and wind turbines.

These companies will raise energy rates so they can collect the money needed to invest in these additional energy sources. By the way, it would cost me $15,000 to solarize my house. Given my current energy bills, it would take more than ten years for my panels to pay themselves.
Roadrunner: You bring up another point. The governor promised 500 thousand “GREEN JOBS”, which were supposed to include solar panel factories.

He promised the jobs, but I guess he didn't promise them in California

The Expert answers:

I love everything about California, except the political culture and they are the FUTURE!? California will be left by workers and businesses alike…leaving the scum behind. Maybe some of them will leave and this state will be great again!…here's to hoping.

Michael li pregunta ...

How much oil do we have left?

Also, when will it all run out if we continue drilling at the rate we are now and which renewable energy source is most likely to rule supreme once petrol and diesel is no longer an option?

The Expert answers:

According to peak oil theory we have about half of the available supply left to us. Like some slush drink so far we have sucked out about 1/2 the available liquid. Now increasingly what is left is mixed with the ice and may be harder to remove.

But how long it will last will depend upon our usage. We could switch to alternative modes of transportation and heating for our buildings. This would eliminate 90% of our oil usage. The remaining 10% of our usage would then have about 10 times the supply to draw from and may last ten times as long as our present usage.

Or as we could continue to use oil as the primary fuel for transportation and a significant fuel for heating. If India and China try to pursue an oil economy like the US, each with 4 times our population the supply may last only 1/10th as long as our present rate of usage assuming we could sufficiently increase the flow.

Increasing the flow (adding more wells ie “drill baby drill”) is like putting more straws into our slush drink. It does not increase the ultimate supply, only the flow. The amount of liquid remaining in our drink is constant, but we can be conservative or use it as fast as possible.

The world has been moving to electrical based energy usage for over 100 years and away from fuel based energy usage. Electrical energy storage and wireless energy transfer are the technological hurtles that will soon be resolved and implemented. Electric vehicles are inevitable. Wireless energy transfer could expand their usage even today: http://www.iav.com/us/index.php?we_objectID=15760

Should politics be one big game or should it be for the benefit of the people? What say you?

In its first 40 hours, the new majority of the House of Representatives kept their promise to voters and passed legislation—increasing the minimum wage for the first time in a decade, empowering Medicare to negotiate lower prices on drugs, cutting interest rates on student loans in half, revoking big oil subsidies and using the money to invest in renewable energy —that provided a down payment for a new direction for this country.

These bills are overwhelmingly popular, and are simply common sense reforms. Yet every one of them—and many more—got held up in the US Senate.

Conservatives boast about the “success” of their strategy in discrediting the new majority. As Senate Minority Whip Trent Lott, R-Miss., put it, “the strategy of being obstructionist can work or fail. So far it's working for us.”

How is it working? It's dragging the reputation of the Congress down to the level of the failed president. Conservatives lie in the road of progress and then complain that nothing is moving.

This values partisan posturing over reforms vital to the country. It must be challenged.

It's time to take the gloves off.

The first step is to expose the obstruction to the American people. Let's urge Senate Majority Leader Harry Reid to force a real filibuster. Keep the bills on the floor and force vote after vote, exposing the obstructionists. We'll organize in states across the country to insure that their constituents know exactly who is standing in the way of progress.
Proud Conservatives need to learn how to read, the freaking point is that the Senate has obstructed the bills , what a freaking tard
All idiots like the Proud Conservative please refer to paragraph 2 before you open your pie hole and make a fool of yourself
Yeah it tells me that a bunch of mindless idiots who can't see past the REAL problem forgot to vote straight ticket to get a REAL majority that could effect change
Indeed, Hendrix also sang
With the power of love anything is possible

Band of Gypsys………..absolutely GREAT RnR
DC John are you really that stupid? The American people VOTED for this agenda so if that's ram rodding something it's the DAMN WILL OF THE PEOPLE , what an idiot

The Expert answers:

Politics should absolutely be for the benefit of the people, because that is the only way that is right and moral and just! But, this is not the case. Politics is actually a big game, and the people are the losers. The people have the numbers, but the people are kept in the dark, and divided, so we are not standing up, as one, against those who have hijacked our government. Until we do, we cannot defeat them. We are all one, and our true power is in realizing this fact…en mass!

Shouldn't McCain be questioning his own energy policies instead of Obama's?

“In 2007, McCain missed all 11 energy -related Senate votes considered key by the League of Conservation Voters, including votes related to automobile fuel economy, offshore Virginia drilling, refinery construction, renewable electricity mandates, energy efficiency, liquefied coal and support for biofuels. The absences prompted the League to give McCain a “zero” rating for the year.”

And Inflating your tires is a tip recommended by all energy experts, Obama merely endorsed it, he never said anything about making that his energy policy.

JonChicago – he has received $200 million from oil companies… he is bought and paid for. how does this make him independent or a maverick?

The Expert answers:

He wouldn't be!! Instead of building solar power towers he wants to build 43 new nuclear plants which cost 3 times the price and put out nuclear waste which nobody wants around them. Also his chief economic adviser is Phil Gramm, who is the former senator that slid the Enron Loophole into the 2000 Energy Bill. To Paulofhouston!! Currently Canada doesn't reprocess it's spent nuclear fuel and it is highly radioactive. Also if it did reprocess, it would be less radioactive but would still have to be disposed of. The cost of Candu nuclear plants are extremely high, even though they are more efficient, they would still produce radioactive waste. Why are you so against solar power tower technology?? Maybe you should check out this website http://www.solarmissiontechnologies.com

Why are there so many social problems in the richest country in the world?

To name but a few, the USA scores lowly in all of the following compared to countries like Japan or Scandinavia (and most of western Europe to a lesser extent):

1) Crime
2) Teenage pregnancy
3) Health/life expectancy
4) Poverty and low income
5) Long working hours culture / less paid hoilday
6) Educational achievement/literacy rates
7) Obesity 8) Environmental pollution eg CO2 per capita, recycling
9) Public transport and renewable energy

The Expert answers:

Interesting Question!! I think it's because in poorer countries people keep to themselves. For example, in the phillipines where i lived, parents would get mad if a teen had a baby because they can't afford it. Obesity occurs in America because people have enough food and people usually take for granted their health. As for Pollution, In phillipines our pollution was so bad I couldn't find a spot of soil that did not have a plastic bag buried or on top of it!

Guillem li pregunta ...

Is China taking a more sensible approach to coal-fired energy?

I have read that since about 2006, China has been 'retiring' many of its smaller, older, less efficient coal-fired plants. To offset the closure of these plants, they are building new, more efficient coal-plants that don't put out as much in the way of pollutants.

As China is rich in coal resources, don't you think that it is wise for them to make the most out of their cheap, readily available energy resource?

China closing down small coal-fired plants
Yvonne Chan in Hong Kong, BusinessGreen, 31 Jul 2009

“Facilities with a total generating capacity of 54GW have been shut from 2006 to June this year, Sun Qin, deputy director of the National Energy Administration, said yesterday.
The announcement follows the release of a Greenpeace report earlier this week that called for China to phase out outdated facilities with a generating capacity of less than 100MW and set a renewable energy target of 30 per cent by 2020.
Sun said the number of plants with a capacity below 100MW comprised 14 per cent of the total proportion of energy -generating units, down from 30 per cent in early 2006.
However, in the meantime new coal-burning plants are still being built at a rate of 70GW per year, although Sun said most of the new facilities have significantly higher levels of energy efficiency than those they replace.
China is the world's largest coal producer and consumer. The fossil fuel accounts for at least 70 per cent of its energy needs – a factor that has led to its top ranking in global greenhouse gas emissions.”

The Expert answers:

We have 2 and half times as much coal as China, yet we don't utilize ours. China is utilizing their resources as are every other country in the world so yes they are taking a more sensible approach IMO.

Maria li pregunta ...

Can you answer five short poll questions?

1. Should the government tax income earners making more than $250,000 annually at a higher rate or the same rate as income earners making less?

2. Should government provide tax incentives for businesses and individuals who use wind, solar or other renewable energy sources instead of nuclear, oil, coal or other fossil fuels?

3. Should the US government support Israel's occupation of the West Bank and Gaza Strip or should the US government support an independent Palestinian state in those territories?

4. Should the government legalize same sex marriages, civil unions, or neither?

5. Should the government keep abortion legal or criminalize it?

The Expert answers:

1. Only tax GOVERNMENT Employees higher that make over $250,000 annually. Flat tax on all the rest.

2. No Renewable Energy is unlikely to be directly econoically viable. The energy required to create the renewable energy infrastructure cost too much energy.

3. Sí! If you give Palestine an independent state either they have to stop the terrorist or be attacked by the Isreal. Do the rulers of Palestine wish to put targets on their house?

4. No! Why should the single taxpayer subsidize others?

5. Over turning Roe V Wade gives the option to the states.

Sandra li pregunta ...

How does my English essay sound?

The topic is “The greatest evil facing our world today”
It is actually a speech to be given in front of a massive crowd

The greatest evil facing the world today is the footprint left on this planet by mankind. The earth is the only one of its kind that we have. Our planet is being worn out by the unnecessary actions that we take each second, minute, hour, day and year. The ridiculous amounts of greenhouse gases that we emit into our once clean atmosphere are going to result in the earth punishing us at anytime she wants. Our survival could be lost in as little as twenty-five years if our behavior towards the environment doesn't change for the better.
The depletion of the ozone layer will be complete within 200 years at the rate it is being depleted now. If this occurs, no life will be able to live on the surface of the earth. There are already some holes in the ozone layer which have caused immense skin cancers and blindness in animals. Frogs all over the world are becoming dreadfully deformed. In addition, over fifty-one acres of rainforest are destroyed by the developed world per minute.
Currently, twenty-five percent of western pharmaceuticals derive from rainforest ingredients although less than one percent of all rainforest materials have been scientifically tested. This shows that the rainforest could have the cure to the vast majority of the diseases that cause troubles in this world. It could have probably been easily ALL the diseases if the extinction rate of all species was not as high as it is now. Currently, over 130 species are lost per day and more than 99.999% of all species that once lived on this earth are now extinct. Nearly half of the world's existing species will be eliminated in the next twenty-five years due to rainforest deforestation.
The amazing thing is that we still consume non- renewable energy much more than we use renewable energy . We consume almost 1.4 million barrels of oil every forty minutes whilst the solar energy that hits the earth's surface in forty minutes is enough energy for the whole world for a whole year. But this does not make us think about the vast amount of energy that has less effect on their world. If we did, the earth would be a much healthier and cleaner place to be in.
Politicians are actually accepting the reality of our situation and are taking actions. They have been given the irritating wake-up call of land loss due to the rising sea levels. Some people are thankful that they are starting to realize our problem. I for one am not. It shouldn't be economic problems that influence their actions, but moral beliefs.

Filed under Wind And Solar Q & A

Lisa li pregunta ...

How much does renewable energy cost?

For domestic and industrial sectors , what are the round figures of renewable electricity rates ?
Where can I find such prices on the net?

Thank you all.

The Expert answers:

It is kind of pricey. But in the long run you will be saving more more. Plus some states actually pay you for your energy.

Robert li pregunta ...

Which is the best rated Masters program in renewable energy management?

I have Engineering and MBA degrees and am trying to find a good Masters/ PhD renewable energy management program (not hardcore engineering). I am considering developed countries eg, Scandinavia, Europe, Singapore, Canada, UK, Australia or the US.

The Expert answers:

In this field you best option is UK or Australia,
Not in Singapore.

I am a Singaporean

Tomàs pregunta ...

Mechanical Engineering at Manchester U or Energy Engineering at Leeds U?

In terms of education quality, student life, crime rates , how welcome are the ppl to international students.. I applied through UCAS and so I get to choose my first and second option. My first option will be either one of both, and second option I think will be Mechanical Engineering with Renewable Energy at Edinburgh U.

The Expert answers:

U of E is very geared towards renewables and Scotland is well placed to derive benefit from them – higher average wind speed and massive currents [compare well globally] in the Pentland Firth.

Overseas students will be welcomed at all your choices.

Universities contain better educated people than the average population and UK has a society tolerant of others.

Should the government subsidize renewable energy development to the equal dollar value that it subsidizes?

the fossil fuel industry? When totalled this would equal hundreds of billions of dollars each year when all carbon fuel subsidies such as exploration, defense and environmental damage are factored in. At that rate a totally new energy infrastructure would be paid for in half a decade and bringing a return on investment.
Lizzy, tax payers of course. The same people who are subsidizing the oil industry to destroy the global environment.
Jim, get your head out of your butt, you're wrong.

What is the possibility of using Al Gore's facial hair as a renewable source of energy….?

….to fuel the planes he is flying all across the country promoting his film? Is it possible that Rogaine, applied to his face, would result in a rapid enough growth rate to reverse his personal contribution to the problem? Or is the energy used to produce the food & clean water to sustain his life in excess of the energy produced by his facial hair such that it is always going to be a net energy loss?

The Expert answers:

Al Gore invented geothermal energy.

Linda pregunta ...

There are some energy sources that can be either renewable or nonrenewable, depending on the manner and rate?

at which we use them.

TRUE
FALSE

The Expert answers:

I believe it is false, but its not black and white so it depends what you were taught in class.

Renewable resources can be used sustainably (only used at the rate it is produced) or unsustainable (used beyond the rate).

Some renewable resources (such as fish, game etc) can be made non renewable if the habitat is destroyed but the resource would still be renewable just not in that location where it would now not even be a resource.

Joseph asks…

Renewable Energy homes ?

The cost of running power lines to my property is $18k, and my rate would be the same as every one else. To me $18k is better spend on solar and wind. So many people think this is impossible to do and are just plain wrong !
Here are two good links to find a better way.

The Expert answers:

Ody

Let me start off by saying we (my family and I) live completely, 100% “off of the grid and are completely self sufficient” using alternative fuels / energy. I was in the exact same situation as you few years ago.

Http://www.agua-luna.com/about_us.html

We do not leave our ranch except about once or twice a year, mainly for travel and vacations.

We raise meat and milk goats, chickens for meat and eggs, ducks for meat and eggs, trap havilina (wild boar pig), rabbit, quail. Brew our own beer from home grown products, preserve our fruits, vegetables, etc. Smoke and jerky the meat, make our own soap, cheese.

There are no utility lines, no water lines, no roads, tv, cell service, etc. On our ranch. EVERYTHING needed is produced here. All electricity comes from 27 solar panels, 2 main wind gens and a back hydrogen generator if needed (typically we can last 9 days with all luxuries of sunless windless weather, hasn't happened yet). Water is caught and storaged from the rain. Hot water is made with solar batch water heaters with an on-demand hydrogen hot water heater as backup. Even our vehicles use alternative energy (2 hydrogen trucks, 1 EV electric vehicle converted).

We've lived self sufficiently off the grid for over 5 years now. In 2003 I left an Engineering position with Boeing, sold 2 houses and most of our positions, purchased a small ranch in West Texas near the Mexican border, built a completely green home using 100% recycled and local (rocks, lumber, sand from the ranch) materials, built a wind generator and some solar panels, built a hydrogen generator and converted the vehicles to run on alternative energy, purchased some goats, chickens, ducks, lamas, etc, a composting toilet, water storage tanks, planted crops and fruit trees and settled down for the long run. We typically don't leave the ranch for 6-8 months at a time, and only then to visit family.

The house is built utilizing natures natural materials, Woodburning stoves, solar chimney, solar AC, solar heating, solar water heating (pool and home), solar stove, solar power, wind power, hydrogen powered back up generator, hydrogen back up water heater, hydrogen stove, 2 hydrogen powered trucks, 1 EV (electric vehicle) and satellite internet.

To see some pics of the ranch you can check out my photobucket below, navigate with the tabs on the left (hacienda, misc, guest house, etc), we're adding every day so be patient and don't laugh at my scraggly winter beard..

Http://s37.photobucket.com/albums/e88/ar…

We also built many small cabins on the ranch that we offer to family, friends and our on-site off-grid workshop guests, including one straw bale, one papercrete, earth bag and adobe, one cob and cordwood, one underground and rammed earth, one log and post and beam and one rock.

I later wrote a several guides on how to build with alternative materials, alternative energy / fuels using alternative methods for next to nothing. Anyone interested can check it out at..

Http://www.agua-luna.com/guides.html

As we have no bills, no mortgage and do not pay taxes (buahaha don't tell anyone) we have little use for money (any extra money saved up usually goes towards vacations as we enjoy traveling to mexico).

If you'd like more info on how you can make the transition easily, let me know.

Hope this helped, feel free to contact me personally if you have any questions if you'd like assistance in making your first self sufficient steps, I'm willing to walk you step by step threw the process. I've written several how-to DIY guides available at http://www.agua-luna.com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Does anybody use Dynowatt for their electric provider in Texas?

I am looking at switching and I saw that they have cheap per watt rates while still being 100% renewable energy . Is this a good one to use? Is there anything I need to know about them before signing up?

The Expert answers:

That sounds fabulous, and I don't see what you have to lose! Here in California, I owe PG&E over $1700.00. Fat chance I'll ever pay that bill. The house stays dark until a fire is lit and everyone sleeps on couches around the fire. Well, whatever,.

17.Plant a tree. Trees help to suck up the carbon dioxide.

18.Teach children the value of our earth. They are the future and you can even learn from each other.
Thank you so much you really saved my life!

The Expert answers:

You have good sentences with some minor errors
CORRECTIONS ARE IN CAPITALS, remove words/ word parts between the [ ]

1. People overused fossil fuels and they did not consider that this natural resource WOULD affect the planet.

2. We believed that water was a renewable resource and we did not pay attention to the way we useD it .

3. People used natural resources faster that they COULD be replaced. They did not think OF the consequences of not taking care of [the - no article here] nature.

(When you use past tense, you have to stay in past tense throughout the sentence.)

4. People used to drive to WORK every day, but now some of them prefer to walk or share cars.

5. People used to leave all the lights on and they also used to throw garbage away IN the rivers. Now people even try to talk to one another about this issue and different ways to help.

If Bush Would Have Spent $2TRILLION On Getting USA Off Of Foreign Oil, Would Terrorists Be Going Broke?

Had Bush spent our grandchildren,s SSi on research and production of renewable energy instead of going to war to protect our oil supply, we would be 7 years into the program by now and well on the way to energy independence.America could have lead the world in green technology creating millions of good paying jobs and eliminating our need for foreign oil. The $ Americans spend on foreign oil/gas provides a large % of the terrorist`s funding.Making this war redundant. Bush could have gone down in history as the president who put America back to work,cleaned up the environment,Halted global warming,Starved Alqidea out of existence, And made America the world leader of green Technology b4 we ended up dependent on China for that too! But………. Instead, He invaded Iraq ,A country that had NOTHING to do with 9-11,Had no WMDs creating 10Xs the terrorists we were facing b-4 9-11.

The Expert answers:

Bush is an oil man. He makes money from oil. He went to war with Iraq because of oil and Saddam's assassination attempt on his father. The welfare of the US was the furthest thing from his mind. He is a traitor.

Chris li pregunta ...

Which is greener, using paper towels or rags?

Paper towels come from a renewable resource. (Hopefully, you have purchased paper towels made from recycled paper.) Paper becomes compost, so it doesn't stay in landfills for as long as plastic. I have heard that using rags, hand towels, or dish towels is greener. But what about the energy and water it takes to wash them? On the other hand, what about the energy , water, and waste that is produced to make paper? I'm looking for some stats and facts so if you are scientist and answer this question bonus for you!

The Expert answers:

Rag because it takes up energy to recycle more than it takes to wash the rags (if you use greenworks you don't have to wash the rags)

Guillem li pregunta ...

For those saying the stimulus “didn't work”, do you realize that is fundamentally changed America?

It was actually a backdoor way for Obama to advance a green agenda. I know some conservatives must hate that because they hate the environment, but green energy is the fastest growing industry in the world. Here is a sample of that..

Last year, exactly two US factories made advanced batteries for electric vehicles. The stimulus will create 30 new ones, expanding US production capacity from 1% of the global market to 20%, supporting half a million plug-ins and hybrids.

And after the credit crunch froze financing for green energy , stimulus cash has fueled a comeback, putting the US on track to exceed Obama's goal of doubling renewable power by 2012.

That's why the stimulus launched the Advanced Research Projects Agency- Energy (ARPA-E), a blue-sky fund inspired by the Pentagon's Defense Advanced Research Projects Agency (DARPA), the incubator for GPS and the M-16 rifle as well as the Internet. Located in an office building a block from the rest of the Energy Department, ARPA-E will finance energy research too risky for private funders, focusing on speculative technologies that might dramatically cut the cost of, say, carbon capture — or not. “We're taking chances, because that's how you put a man on the moon,” says director Arun Majumdar, a materials scientist from the University of California, Berkeley. “Our idea is it's OK to fail. You think America's pioneers never failed?”

An amazing article on the stimulus, lots of stuff you just don't hear about in the main stream media. http://www.time.com/time/magazine/article/0,9171,2013826,00.html#ixzz1VjXpLSaA

The Expert answers:

Let's say that everything you wrote is 100% true.

Here's where you and I still disagree: It is immoral and illogical for a few oligarchs in Washington (Republicans Included) to force the citizens to pay trillions of dollars for things they don't support. If you refuse to pay taxes for the stimulus, or wars, or welfare, or drug enforcement, or nation building, or foreign aid, or home loans, or student loans, or the Post Office, then armed men will come to your house and take you away to prison.

Their plan is put in place only through force, and only by infringing on everyone else's property (money).

Even if green jobs are the greatest thing since toast, then why can't people like you invest your own money and leave the rest of us out of it? Then you can reap the benefits without having the government steal our money on your behalf.

Do you really think it makes sense to add trillions of dollars to an already unsustainable debt so you can have your green jobs? Do you really think that it is ok to rob people if you are going to do something that, you think, benefits them?

For the record, your stance has no similarity to the real meaning of the word “liberal”. It is far better described as “authoritarian”.

The Expert answers:

Part 1:

“Australia's BOLD plans for a carbon emission trading scheme are under threat. CriticS say it would cost jobs and promote economic uncertainty.”

(Here a man gives the news story with an Australian accent.)

“Okay, that was a VOA news clip, because today is Monday.”

Youre right, they probably received the news story from Voice of America.

Part 2:

“Okay, that was a VOA news clip, because today is Monday.”
“Mm hm, and did you know that Australia has, I think, the majority of their power plants as coal-firing power plants.”
“Still?”
“Yeah.”
“That's the majority, huh?”
“That's why they're such high EMITTERS of greenhouse gases.”
“Hm hm.”
(Speaking Korean.)
“Yeah, unless, you know, they start investing into some nuclear power plants.”
(Korean again.)
“Yeah, and you know, Australia is one of the, I guess, few countries where they have such varying climate zones and territories, and, you know, different landscapes, that they could probably use a lot of renewable sources — energy sources such as sunlight because they have the desert, they have a specific region where there's a lot of wind, and they also have tons of LAND, you know, the outback wilderness is another resource they could use.”

The male speaking says “you know” a LOT!
That's what they call a “verbal tic,” something people say or a sound they make unconsciously while they're gathering their thoughts and deciding what to say next. Some people say “um,” some say “uh,” President Obama says “ah” : D , others say “er” … And this guy says “you know.” If you take out all of the “you knows,” it makes his speech much easier to understand. He might not even realize he says it!

Your corrections:
emitters
you know (means nothing)
investing (no THE)
nuclear
“… One of the few countries where they have such varying climate zones and territories, and (you know) different landscapes.”
“… Because they have the desert…”
“… And they also have tons of LAND…”
” …the outback wilderness is another RESOURCE…”

Sandy li pregunta ...

Don't you think that India has a lot of lessons to learn from recent fearful Japanese experiene?

Earthquake, tsunami and a nuclear emergency, what has happened in Japan is extremely sad. My thoughts are with the people of Japan. The crisis at Fukushima continues to be a race against time, and is clearly not under control.

But Maharashtra committed to set up a nuclear power plant at Jaitapur! The nuclear reactors planned in the country, especially in Jaitapur, Maharashtra needs to be reviewed. It is also an earthquake prone zone, which the authorities are trying to downplay.

When Japan with its advanced technology is struggling with the situation, imagine what could happen in India? (recall the horrid impact of Bhopal toxic gas leak, due to lax safety systems to protect staff and public, that resulted in the biggest industrial tragedy of our times)!

Nuclear energy is a gamble and the risks can be deadly. The Government needs to invest in renewable energy and energy efficiency, that is not only environmentally sound but also affordable and reliable.

The government needs to know that people all across the country support those opposing the nuclear plant in Jaitapur.

People in Jaitapur don't want this nuclear plant. Green Peace India is taking a signature campaign in the cause against nuclear installations in general and in the Maharashtra site in particular.

Also be informed:
Nuclear power could cost trillions over renewables Scientific American, June 19, 2009:
The analysis factors in studies from Wall Street and independent energy analysts estimating the efficiency of renewable energy at 6 cents per kilowatt hour versus 12 to 20 cents per kilowatt hour for nuclear. Cooper says those costs will fall on either ratepayers through higher electric bills or on taxpayers through large subsidies.

Don't you think we should leave a safe and secure place for our children and grand children?

The Expert answers:

Well!!!!!!!!

You are correct….

Nuclear Plants may serve as a heavy threat to lifes in case of explosion..

BUT….
Why are nuclear plants being commissioned?
For Energy!!
There is an increased demand for Energy.. That provides the need!!

Today, Thermal (Coal) and Hydel (Water) power plants are the major sources of energy..

The resources for the Thermal energy are being continuously exploited and is being depleting at aa faster rate..
In case of Hydel Energy, it is primarily dependent upon the Water.. Due to the advesre effects in climate, caused due to thermal pollution, water resources are being dried up or getting worse and scattered..

What are the remaining Options?

* Solar Energy:
India can utilise a maximum potential of Solar Energy as the penninsula witnesses Sun atleast 270 days/year!!

* Tidal Energy: This Oceanic Energy can also be very well utilised in India

* Energia Eòlica:
Available only at few places in India . But, still we can utilise the energy disspiated by a moving vehicle too!!

* Biomass Energy:
This is also a viable option for Energy resource. India has a huge population, and the energy dissipated by the population itself can serve as a Saviour of energy

* Geothermal Energy: Energy from hot springs beneath the crust.

It is quite evident that people themselves can install small power plants in their home using renewable energy.. For instance:
* Solar Panels at top of the roof for Solar lighting
* Biomass generator for cooking food (instead of / a supplement to LPG)
* Bicycle/ Solar Power to charge the mobile phones
* Wind Energy (a small fan ofcourse) to make some lighting

This can make us self sustained in Energy..

BUT……….

Who is ready to install renewable Energy ?

People always want to have the environment clean and threat free. But, no one seldom uses any measures for that..

Most people prohibit Electric / Solar Cars just because they are not aesthetic!!
Similarly, they turn away from Solar Energy / Wind Energy just because of ots inital cost!!
(Though Govt provides subsidy for that)

Hence,

Unless People willingly come front to install small renewable energy power plants in their homes, or stop using Energy at their will, Energy Demand will continue to increase…

That implies, we cannot stop the Govt. From installing nuclear power plants…

I am ready.. How many are????

PS:
I am not suggesting to convert everything into renewable energy.. Atleast a small part!!

Your Questions About Wind And Solar

Filed under Wind And Solar Q & A

Richard li pregunta ...

Creative ways to generate energy?

Besides the well known renewable energy sources (solar, wind , hydrothermal, etc), what are some creative/unique ideas to generate energy ? Whether large scale (like for a company), or that can be done in a home? For example, riding a stationary bike that generate electricity from the turning of the pedals.

The Expert answers:

Geothermal energy is one you didn't name… If only we could start making more low pressure devices…lol.

Um, you could always use weights to do the same thing as a bike(if you're a weight lifter). Instead of using batteries you could use hydraulics to store and use the energy to power something. I know that hydraulics are pretty awesome if you set them up right. You could probably even install a pressure system that forces oil into an accumulator every time you park on it with your car, they use those in some shopping parking lots(so i've heard). There is a ton of power in water, so if you're near a water source you could probably making a renewable energy source there.
Steam power is great for someone that is certified. It's pretty dangerous, but the power is more than sufficient to run a home if you have a big enough system.
Perhaps you want to capture lightning?
You could come up with some new ingenious way to do it, powering whole cities.
Tesla had some really awesome ideas.

i want to prepare a model related to renewable sources of energy.?

It is should not like solar cooker or wind mill. I just want something different and good of the school level and not more than that.

A little can be taken.

The Expert answers:

I'd make a wind turbine surrounded by fields of corn. That would showcase two forms – wind and ethanol. You could also have a little farm like “off in distance” sort of that has like a solar panel roof or something. Just a thought :)

Go green!

Chris li pregunta ...

What is the best renewable energy source?

Please, just answer this if you really KNOW :) For a country that has sun, wind and geothermal areas, and lots of it all, in which order should these resources be used as energy sources , considering cost of production, land use and amount of energy production

The Expert answers:

This answer is not as simple as which one is best… There are many factors that would largely be based on geographical Location. For instance it would not make much sense to install solar energy collection systems in areas that too far north because they simply do not get enough direct sunlight to be viable. Likewise placing a wind system in an area where sustained winds are rare would do no good. The other thing to consider is where are the consumers for the energy located in comparison to the locations of the energy system. Placing large wind farms in the Dakotas ( two of the states with the largest wind sources in the nation ) really doesn't do the nation any good because you cannot transport the energy very far. The neighboring states is about all the further the benefit would reach. The same goes for placing large solar collection stations in Arizona or Nevada. You could power nearby cities but you really can only transfer the energy so far.

That is based on large scale energy collection systems. If you are interested in something residential then it is a different story.

Currently the best of the 3 options may surprise you… It is GeoThermal. But not geothermal energy production… Merely usage. If you were to install a Ground-source heat-pump in your home you would save up to 70% on the energy you currently use. These systems are proven and have been around a long time. The price range is reasonable NOW unlike other options. Prices can range from $2500 + for install depending on the situation and if you need to tear-out an existing system. The land usage is underground so you just need space to have a crew come in and dig. The unit would pay for itself in savings within a few years. Total amount of energy that the system would save is much more than the amount it takes to put the system in place (thus giving it a smaller Carbon footprint). Even though this system does not produce energy it uses existing energy and greatly reduces the amount of energy that a residence requires.

Photoelectric solar panels are very inefficient and very expensive to produce. The amount of energy that it takes to produce a solar panel is actually MORE than the amount of energy that the panel will be able to produce within it's lifetime. ( given an average lifespan of the panel and current technology ) While the panel may save YOU money and energy, it costs the enviroment more energy than it can recoupe.

A Wind system costs less in money and energy to produce than solar but still has some of the same draw backs. Both systems require battery banks and extra wiring systems before something could be used. Wind and sun are both non-consistent sources so days when the sun is weak or the wind is down you receive no benefit.

All three systems are currently only supplimentary at best. We don't have the technology to use any single source by itself completely. Solar and Wind both require better energy storage techniques to suppliment days of low production. Geothermal heat/cooling systems still require another source of energy. Solar systems need to become much more efficient before they are truly viable except for providing power in very remote locations.

In terms of providing large scale benefits to the masses using industrial sized verions of these energy sources we need to find ways to transport energy over greater distances with better super-conductors or microwave technology or something new.

Currently I would list the three sources in order of energy benefit in this order.

Geothermal
Wind
Solar

Joan pregunta ...

Can anyone explain to me the negative aspects behind renewable energys such as wind and solar?

There has been consistent talk about the pros of renewable energy source, but just to get a good understanding of the argument I would like to hear some of the negative aspects associated with this energy .

The Expert answers:

Expensive, takes a lot of land to make a small amount of power, and inefficient. Neither will work everywhere.

Donald pregunta ...

Does it take more water to deliver electricity from renewable or nonrenewable energy?

I've heard that it takes water to power anything, so does it take more water to deliver electricity from renewable sources (solar, wind ,geothermal,tidal) or from nonrenewable sources (coal,natural gas,oil)?

Please include web sources , this is for a research project.
(Does it take any water to TRANSFER energy from sources )

I did not mean does it take water to collect energy .

The Expert answers:

The actual distribution of energy, from a power plant to your door does not require water. Water is required for the manufacture of nearly all physical goods, including those goods/equipment that generate electricity. Solar cells, wind turbines, gas turbines, etc all required water when they were made.

Solar panels do not require water, neither do wind turbines. Some other solar methods do require water.

The actual generation of electricity requires varying amounts of water, depending on the process. Any steam turbine requires very high purity water that is heated and used to produce power. Typically the water is recycled in the system, but it still uses significant amounts. Water is also used to cool the steam so it can be re-heated. This water is commonly passed through once (think of taking flow from a river or ocean). In gas turbines, water can be injected to reduce emissions and increase power output. Hydroelectric develops all power from water.

Susan li pregunta ...

are main goverments constructing renewable energy plants?

countries like usa and european ones. are they building wind farms and that. what ones?

and also what is the highest renewable energy source for one country?

The Expert answers:

Yes, a lot of countries are wasting money on wind and solar.

The only 'renewable' sources of power that are actually reliable enough to be worth having or hydroelectricity and geothermal power but not all places have the geology needed for them and hydro has something of a bad reputation (well deserved given the environmental impact and what happens when dams fail).

As for who uses the most renewables, Norway has a lot of hydro and Iceland uses geothermal extensively. Denmark has managed to get about 20% wind capacity but hasn't even shut down any coal power plants and at the moment pretty much just sells the wind power to Norway really cheap where it's used to pump water uphill.

Guillem li pregunta ...

Which two renewable energy sources depend on the weather?

solar
tidal
wind
biomass
geothermal

The Expert answers:

Geothernal is the only one not readily effected by the weather.
Tidal does not depend on the weather but may be effected by it. Think hurricanes.

Biomass needs sunlight and weather to grow.
Wind needs weather to work at all.
Solar works best under clear skies.
Hydro needs rain.

Joseph asks…

which is not a renewable energy source A.geothermal B.hydroelectric C.natural gas D.wind?

The Expert answers:

C. Natural Gas
Natural gas is composed primarily of methane (CH4). It does contain other chemical species, such as butane and propane. If the mixture is comprised only of these species, it is called dry natural gas, as there will be no liquid components at standard pressure and temperature. There might also be some other organic components, such as pentanes, that are mixed in with these species. These heavier species are normally liquid at standard temperature and pressure, and comprise what is called natural gas liquids. Natural gas might also be mixed in with non-hydrocarbon compounds, such as water vapor, carbon dioxide, and hydrogen sulfide. If so, it forms what is called wet natural gas, and requires some processing before it can be used.
Natural gas comes from the decomposition of organic matter, just like oil and coal. Unlike oil and coal, though, it can come from almost any organic matter, whereas coal comes only from plant matter and oil comes almost exclusively from plankton and microplankton remains. Natural gas can come from both of these sources as well. This is why you often find it associated with both oil wells and coalmines.
Fig 1: Jefferson County Landfill (DOE)
Natural gas can also come from unconventional sources, as well. It is produced by dead plant matter decay in swamps and rice fields. Animals, such as cattle and termites, produce large quantities as a by-product of digestion.
